I've heard of this notion of the "Career Sweet Spot" before. The place of intersection of these things:
1. Your strengths and skills.
2. Your passions and interests.
3. Your purpose and calling.
Where those three overlap is a place of fulfillment.
I've been rolling these around in my head again. Evaluating life direction...even if it doesn't mean a change of job (although that'd be nice some day)...just to have a better sense of who I am and what I'm made to do in my life. Good stuff!
