Commitment Versus Attachment

When I feel committed, it gives me 
purpose, energy, direction.
But to fulfill my commitment,
especially if someone else is committed 
to the opposite cause, 
I need to understand all angles, all sides. I need to not let disdain, and scorn, and hate get in my way. It's a lot like practicing law.
Attachment feels different.
It feels like a clingy state. There’s something I want, I think I know why,
and I’m sure I know best.
 I’m not learning, not open, and often, not understanding.
There’s a tightness - it’s inside the word itself -
and separation, and sometimes, hate.

Maybe commitment is about being fierce, and attachment is vicious. Maybe commitment is about caring and attachment isn’t. I don’t know for sure. What is the difference for you?
