Well, while I find myself often swinging between "curiosity" and "anger", I don't really see those as being driving forces in my life anymore.
These days, I would have to attribute my motivation to simple stubborness, and maybe a dash of lust. And by lust, I mean a lust for everything I find desirable. Sheer, wanton gluttony. Yee-haw.
Hedonism seems to be a rather effective cure for depression, too.
