Photography Flying does it for me.
No chance to get bored when you're continually working out how to stop hitting hills or wires. And get the perfect shot. And trim the plane when the photographer's ass is over the trim wheel. And answer ATC when they ask for a position report just as you're plotting a spot on a GPS or a map. And your map has just blown out the door (haha!)
And putting on lip gloss to look gorgeous when you land
You get my point. Love it.
