What's your favourite active career?

My sims are mostly self-employed (all of the choices work for me). I like the flexibility. Frequently, money isn't the priority and neither is advancing the career particularly far. Substantial income is more likely to come from real estate and/or their cute and useful dogs who hunt up valuable stuff.

The other active careers are too demanding/rigid for me unless I'm only playing one sim, and I'm never doing that, so I haven't touched one in a pretty long time.
