You should do what you love and thereby love what you do. If you don't, take a step back as you may need to recalibrate a bit (or a lot). It's a healthy and productive exercise, if only to reaffirm your current direction.

EDIT: I don't mean to get all meta, but it's not about the ideal of others but rather what makes you happy as an individual. Anyway, that's the way I rationalize it all.
