From Ummu Hani R.anha:

أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَوْمَ صَلَّى سُبْحَةَ الضُّحَى ثَمَانِ رَكَعَاتٍ كَانَ يُسَلِّمُ مِنْ كُلِّ رَكْعَتَيْنِ

Meaning :

That Rasulullah SAW prayed dhuha eight rak’ahs, performed with salam for every two rak’ahs. (Hadith narrated by Abu Daud, al-Tabarani, Ibn Khuzaimah, and al-Baihaqi.)

2. Smile

‍“Smiling in your brother’s face is an act of charity” (At-Tirmidhi; Declared Authentic by Al-Albani).

“When Allah’s Messenger went to bed, he used to sleep on his right side.”[Bukhari]

One of the main points to consider when a person wants to have a productive, blessed day is to look at how you go to sleep.

The Prophet was most successful in how he spent his days; the way in which he took to his sleep played a role in helping him to be our leader and our guide.

2.Sleep in the state of Wudhu (Ablution)

2. Giving sadaqah

   even if you have less money it is beneficial for us to give sadaqah as well because Allah can give you more if you giving other with sincere’s heart. Sadaqah is also known as a voluntary act of charity that is given for the sole purpose of pleasing Allah (swt) and without expecting anything in return.

The Prophet (saw) said “Give Sadaqah without delay, for it stands in the way of calamity.” (Tirmidhi)

When wearing shoes or slippers, we were taught by the Prophet SAW to start with the right foot. On the other hand, the left leg comes first when wanting to take it off.

This is as narrated from Abu Hurairah RA that the Prophet SAW said,

"If you wear sandals, put your right foot first, and if you take them off, put your left foot first. If you wear them then you should wear both or not wear both at all." (Hadith narrated by Bukhari and Muslim)

2. Enter and exit the toilet by reading a prayer

Recite the following prayer before stepping into the toilet with your left foot:

"Allahumma inni a'uzubika minal khubusi wal khaba'is'"

Meaning: "O GOD, I seek refuge in YOU from the temptation of male and female devils." (Hadith Narrated by Bukhari and Muslim)

After that, get out of the toilet with your right foot while reciting:

"Ghufranak"

Meaning: "I beg forgiveness from YOU." (Nasa'i Narrated Hadith)

3. Be polite when eating

Before and after eating, we are circumcised to pray. In fact, it is enough to just read bismillah.

Another sunnah when eating and drinking is to start with the right hand and take the food closest to us. Not blowing food or drink, licking fingers to clean leftover food, not criticizing food when you don't like it and not wasting the food.

A smile is the easiest 'sedakah' that everyone can do, and the Messenger of God, may God bless him and grant him peace, was the most generous person with an endless smile on his face.

This makes people around him happy.

Abdullah bin al-Harith r.anhu said,

"I have never seen someone who smiled more than the Messenger of God." [Hadith Narrated by At-Tirmizi]

2.Read Al-Quran

By reading the Qur'an we will find tranquility and peace of mind. In fact, reading the Quran can increase the level of love and piety towards Allah.

Prophet Muhammad SAW said:

"Read the Qur'an because indeed the Qur'an will come as an intercessor for its companions (those who read it)." (HR Muslim)

3.Put Right Foot First When Wearing Sandals and Left Foot When Removing Them

The Prophet Muhammad SAW encouraged each of his followers to put the right limb first and then the left limb in everything they do on a daily basis.

"If you wear sandals, put your right foot first. And if you release it, then put your left foot first. If you wear them, you should wear both or not wear both at all." (HR. Al-Bukhari and Muslim)

Follow the teachings of the Quran, for there are no better teachings and there is no better book than the Quran 😊. Act upon the guidance and teachings of the Quran.

This is what I could think of at this current moment in time with my current knowledge though there are many scholars and people more knowledgable than me. If this you wanted a more specific answer then let me know and if you need help with anything feel free to ask. ☺️

Al-Ahzab 33:21 Quran

لَّقَدۡ كَانَ لَكُمۡ فِى رَسُولِ ٱللَّهِ أُسۡوَةٌ حَسَنَةٌ لِّمَن كَانَ يَرۡجُواْ ٱللَّهَ وَٱلۡيَوۡمَ ٱلۡأٓخِرَ وَذَكَرَ ٱللَّهَ كَثِيرًا

There has certainly been for you in the Messenger of Allah an excellent pattern for anyone whose hope is in Allah and the Last Day and [who] remembers Allah often.

Sahih al-Bukhari 3759, 3760 Hadith

حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، عَنْ سُلَيْمَانَ، قَالَ سَمِعْتُ أَبَا وَائِلٍ، قَالَ سَمِعْتُ مَسْرُوقًا، قَالَ قَالَ عَبْدُ اللَّهِ بْنُ عَمْرٍو إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم لَمْ يَكُنْ فَاحِشًا وَلاَ مُتَفَحِّشًا وَقَالَ ‏"‏ إِنَّ مِنْ أَحَبِّكُمْ إِلَىَّ أَحْسَنَكُمْ أَخْلاَقًا ‏"‏‏.‏ وَقَالَ ‏"‏ اسْتَقْرِئُوا الْقُرْآنَ مِنْ أَرْبَعَةٍ مِنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ، وَسَالِمٍ مَوْلَى أَبِي حُذَيْفَةَ، وَأُبَىِّ بْنِ كَعْبٍ، وَمُعَاذِ بْنِ جَبَلٍ ‏"‏‏.‏

Narrated `Abdullah bin `Amr: Allah's Messenger (ﷺ) neither talked in an insulting manner nor did he ever speak evil intentionally. He used to say, "The most beloved to me amongst you is the one who has the best character and manners." He added, " Learn the Qur'an from (any of these) four persons. `Abdullah bin Mas`ud, Salim the freed slave of Abu Hudhaifa, Ubai bin Ka`b, and Mu`adh bin Jabal."

This is from Sharh Saheeh Muslim (3/149): It is mustahabb to start with the hands before the feet, and to start with the forefinger of the right hand, then the middle finger, then the ring finger, then the pinkie finger, then the thumbs, then to move to the left hand and start with the pinkie finger then the ring finger, until all the fingers are done, then to move to the right foot and start with the smallest toe on the right foot and end with the smallest toe on the left foot. And Allaah knows best.

2) Sometimes I will follow the proper way if drinking

Prophet Muhammad (Sallallaho Alaihi Wasallam) said: "Sit down and drink." (Hadith Muslim) and also said: "None of you should drink while standing; and if anyone forgets, he must vomit."

Prophet Muhammad (Sallallaho Alaihi Wasallam) said, "Do not drink water only in one breath, but drink it in two or three breaths."

3) Start doing some of the things with the right hands

“The Prophet used to like to start from the right side on wearing shoes, combing his hair and cleaning or washing himself and on doing anything else.”

Sahih al-Bukhari (168)

1. Use of Siwak:

   • The Messenger of Allah (peace and blessings of Allah be upon him) said, Siwak cleanses the mouth and pleases the Lord. (Reported by al-Bukhari in his Sahih, 2/274, and by Ahmad, 6/47, and al-Nasai, 1/50. Its isnad is sahih, see al-Irwa 1/105)

   
   

2. Reading Soorat al-Ikhlaas, al-Falaq and an-Naas before sleeping.

   • It was narrated from ‘Aishah (may Allah be pleased with her) that when the Prophet (blessings and peace of Allah be upon him) went to his bed every night, he would put his cupped hands together, then blow into them, then recite into them Qul Huwa Allahu ahad, Qul a'udhu bi Rabb il-Falaq and Qul a'udhu bi Rabb il-Nas [i.e., the last three surahs of the Quran), then he would wipe his hands over as much of his body as he could, starting with his head and face, and the front part of his body. He would do that three times. The word translated here as blow refers to spitting lightly and drily. Narrated by al-Bukhari (5017).

   
   

3. Recite Ayah-tul-Kursi after every prayer

   • it was narrated that Abu Umamah said: “The Messenger of Allah (peace and blessings of Allah be upon him) said: “Whoever recites Ayatul Kursi immediately after each prescribed prayer, there will be nothing standing between him and his entering Paradise except death.” This is how it was narrated by al-Nasai in al-Yawm wa’l-Laylah, from al-Hasan ibn Bishr. It was also narrated by Ibn Hibban in his Sahih from Muhammad ibn Humayr, who is al-Homsi, and is also one of the men of al-Bukhari. The isnad meets the conditions of al-Bukhari.

Prophet Muhammad says, “to smile in the face of your brother or sister is an act of charity.”

2. Sit down when drink

“Allah’s Apostle forbade that a person should drink while standing.”

Prophet Muhammad (Sallallaho Alaihi Wasallam) said, "Do not drink water only in one breath, but drink it in. two or three breaths."

3. Recite Al-Mulk before sleeping

Anas ibn Malik reported Muhammad as saying, "There is a Surah which will plead for its reciter till it causes him to enter paradise."

The benefit for recite Surah Al-Mulk are provides protection in this life and hereafter but will protect you in-between.

When we drink while standing, our bodies suffer from indigestion due to the speed and impact of the food going straight to the lower stomach from the food canal. Thus, it is encouraged to follow the sunnah by always sitting down whenever we eat or drink.

Anas reported Allah's Apostle (S.A.W) disapproved the drinking of water while standing. (Sahih Muslim)

2) Dusting off the bed twice or thrice with the edge of a cloth before lying on it followed by this dua:

بِاسْمِكَ رَبِّي وَضَعْتُ جَنْبِي، وَبِكَ أَرْفَعُهُ، فَإِنْ أَمْسَكْتَ نَفْسِي فَارْحَمْهَا، وَإِنْ أَرْسَلْتَهَا فَاحْفَظْهَا، بِمَا تَحْفَظُ بِهِ عِبَادَكَ الصَّالِحِينَ

translation:
“In Your name my Lord, I lie down and in Your name I rise, so if You should take my soul then have mercy upon it, and if You should return my soul then protect it in the manner You do so with Your righteous servants.”

Al-Bukhaari (6320) and Muslim (2714) narrated that Abu Hurayrah (may Allaah be pleased with him) said:

The Prophet (peace and blessings of Allaah be upon him) said: “When one of you goes to his bed, let him dust off his bed with the inside of his lower garment, for he does not know what came onto it after he left it. Then let him say the dua as mentioned above.

The dhikr after salah referred to in the question has been reported in a hadith reported by Abu Hurayrah from the Messenger of Allah (peace and blessings of Allah be upon him): “Whoever glorifies Allah (says Subhan Allah ) thirty-three times immediately after each prayer, and praises Allah (says Al-hamdu Lillah) thirty-three times, and magnifies Allah (says Allahu akbar) thirty-three times, this makes ninety-nine, then to complete one hundred says La ilaha ill-Allah wahdahu la sharika lahu, lahul-mulk wa lahul-hamd wa huwa ‘ala kulli shayin qadir (There is no god except Allah Alone, with no partner, His is the power and His is the praise, and He is Able to do all things) his sins will be forgiven even if they are like the foam of the sea.” (Reported by Muslim, 939).

2.recite surah al mulk every night

Abu Hurayrah narrated that the Prophet (peace and blessings of Allah be upon him) said: “A surah from the Quran containing thirty verses will intercede for a man so that he will be forgiven. It is the surah Tabarak Alladhi bi yadihi’l-mulk [i.e.,Surat al-Mulk ].” (Narrated by al-Tirmidhi, 2891; Abu Dawud, 1400; Ibn Majah, 3786

3.recite surah ar rahman or every morning

for surah rahman:

The Prophet (Sallallahu Alayhi Wasallam) went to the companions and recited Surah ar Rahman but they were all quiet. He told them that he went to the jinn and recited it to them and they were responsive. And when he would recite the verses ‘And which of the favours of the Lord will you deny’ the jinn would respond ‘There is nothing among your bounties that we can deny, all praise belong to Allah’

1.Simplicity in Outfits: Although individual tastes differ, the Sunnah upholds the values of modesty and simplicity in clothing. This teaches Muslims to prioritise decency and respect over excess and to be aware of how their clothing affects both them and other people. It doesn't force people to wear a certain way; instead, it helps them cover in a way that suits them and their ideals. This practice cultivates a feeling of self-worth that is independent of appearances and promotes inner dignity.

2.Mindfulness in Eating: The Sunnah encourages mindful eating, emphasizing intention and respect for food as a blessing. This is more than just good manners; it promotes moderation and thankfulness for food. It is demonstrated by customs such as eating with the right hand, saying "Bismillah" before meals, and not wasting anything. By encouraging a balanced relationship with food, this mindful approach enhances our bodily and spiritual well-being.
