All my issues with procrastination come from some deep internal issues, for example, an aversion to working hard, sleeping early, or wanting to spend a lot of time on games as some sort of status symbol.
A lot of these come from mental scars in our past, or even the wrong cultural conditioning. Basically just think what we would do if we were in complete control of ourselves, and why we're not doing that. And then dig really deep to find out where. You'll definitely know when you strike the nerve - it can trigger a sudden rage or tears. But hitting that nerve reduces the control it has over you.
