How can one please God Almighty, and what should a young man do when he delays prayer due to his night work, and is his prayer valid if not performed in the mosque, and what is the ruling on his watching TV series?

He congratulates you on your repentance, fasting, and prayers, and gives you glad tidings that Allah Almighty draws near to those who draw near to Him with sincerity and devotion. He advises you of the following: Sincere turning to Allah and purity of intention, performing the obligatory duties, especially prayer on time and in the mosque whenever possible, repenting from watching forbidden TV series, adhering to the remembrance of Allah and supplication, and choosing righteous companionship.
