I will improve myself

A quick intro about myself:
I am 21 male.I am a science research student. I haven't done any sorts of solid/liquid/gaseous abuses and will never start it either. I am 5 feet 6 inches. Not muscular kind of thin guy . Also with fat just around my belly region. I am entitled to quit often eat junk food at times. Regarding my porn habits, I am a vanilla plain straight (sometimes lesbian) porn viewer. I masturbate a lot. 1 or 2 times a day, daily. I sleep at 2-3 at night. Have classes from 9. I skip breakfast. Then Have some noodles outside sometimes. Most of food I have from hostel mess. I live in a room with tripple sharing. I am virgin and never even kissed or had gf. But that is because I only want serious relationship which should be beginning from tested friendship of 2-3 years .

My academics is being affected. Please help me That my intro. As you have done so much more, just guide me how to get rid of this pmo addiction.
