Feelings are irrational and can't be trusted to base any decision of importance on.
Well, I wouldn't go that far. I think that it's important for everybody to do what makes them most happy in life, and happiness is after all, just a "feeling." I would make important decisions about my future based on which options are most likely to make me happiest. Again, I just don't expect others to make important decisions based on what makes me happiest.
