Jobs that won't even seem like work for Leos...
A career is an extension of who you are. It must be worthwhile and exciting. No cubicle farm for you! Put your stage presence to work as a musician, actor, or other creative artist.
You also crave status and like to impart your knowledge to others, so the law or teaching might be more your style. Love animals? Try an animal rights group. Or politician - is it a surprise that Arnold Schwarzenegger and Barack Obama are Leos?
It goes without saying that you need room for advancement. If you can't be the boss someday, it's because you aren't interested!
