The most key thing I've found over time, as far as enjoying being a fachead, is "being backed up/supported by staff." Whether for plot or disciplinary purposes.
I currently am, and it's great. Lots of fun. When I haven't been, it's a nightmare.
Also I generally think "what you find fun in RP" will inform your happiness/success as a leader. It's helpful to actually enjoy the kind of RP you get playing a leader: delegating, guiding, etc. If you RP to solve plots and use all your cool powers, don't be a leader. A lot of leadership is giving up the ability to do that so that your group people can.
I find a lot of people who make this mistake wind up being unhappy in the job, or make their group unhappy, or both.
