I started taking flying lessons about 7 years ago, and about 4 years ago I got my instructor certificate. I taught people how to fly on weekends and after work until my 1500 hours came up, then I applied to an airline and got a job.

The flight instructor thing was actually occasionally rewarding, especially when people landed the airplane by themselves for the first time. Seeing the look of joy and satisfaction on their faces is one of the better parts of this whole flying thing. :)
