- but -

I want to replace compulsion with impulse. I'm not even sure there's a difference. 

(driven by/driven on)

the things I can do, the things I cannot do. 

How to differentiate between don't and cannot?

This week I've had experiences of bliss. (Is that the word I mean?)

I still don't do what I think I want. I am driven but I sure as hell don't follow.
