First time I stopped, because I got stuck. I didn't have Internet at home, so I had nobody to ask for help. Second time I stopped, because of university exams.

First time I stopped, because I got stuck. I didn't have Internet at home, so I had nobody to ask for help. Second time I stopped, because of university exams. I was studying something completely different at the university and when exams came, I dropped the programming and didn't pick it up after. Third time was the lucky one. I made programming my most important priority and I didn't stop. Also, I had Internet, so I could ask for help.
