I wrote this comment once...

Logically, I should be the least productive scholar because, while somewhat intelligent I am told, I am lazy and inefficient. So I am productive scholar in spite of my laziness and inefficiency. When those qualities have gotten in my way, I have found a way around them, so that now I am reasonably efficient, though still damned lazy. I also tend toward depression, but I can write my way out of it. Sometimes I think I could have written much more if I weren't so lazy and inefficient and depressive. Maybe so, but I think that I would have, if I had wanted to badly enough.
