When a person realizes that he is moving away From the Lord by disobeying his Lord and he wants to purify himself and raise his level spiritually — This is the right time to repent and bring yourself closer to your Lord.
Make the most of these Feelings of shortcoming to push you to strive; don’t let them make you sink to a lower level or be content with the status quo and not try to change.
Always be conscious of Allah, because Allah says — “O you who believe! Fear Allah (by doing all that He has ordered and by abstaining From all that He has Forbidden) as He should be Feared. (Obey Him, be thankful to Him, and remember Him always,) and die not except in a state of Islam [as Muslims (with complete submission to Allah)].” (Al ‘Imraan 3:102)
