brother. Perhaps you are thinking too much and making it too complicated. What we need to do is. Pray Salah 5 times a day, fast during Ramadan, Calculate Zakat and disperse it accordingly every year, Perform Hajj if possible, Give Sadaqa without anyone knowing, Recite the Quran daily for a few mins atleast, Pray Tahajjud if possible, Zikr of Allah, Obey ones parents. Stay away from alcohol, Zina, murder, slandering etc.
