How can one get rid of masturbation and watching pornography, become regular in prayer, and control anger, in order to regulate life and work for the hereafter?

Praise be to Allah for your awakening. Know that sincere repentance erases sins and makes the repentant person like one who has no sin, as the Prophet, peace and blessings be upon him, said: "The one who repents from sin is like one who has no sin."

You must repent from abandoning prayer, masturbating, and watching prohibited things, feeling remorse, and resolving not to return to them. What will help you with repentance are: 1. Continuously reflecting on the attributes of Allah and His awareness of you. 2. Reflecting on the Last Day, Paradise, and Hellfire. 3. Choosing righteous company, and striving in remembrance (dhikr) and supplication (du'a). 4. Marriage, if possible, or increasing fasting. 5. Staying away from the causes of sin.

To overcome anger: Strive to be forbearing and suppress your rage, and increase in supplication. Whoever strives against his soul and seeks Allah's help, Allah will help and guide him. Do not despair if you falter, and strive to seek religious knowledge and attend its gatherings.
