I see so many on this forum (myself too at one point) fretting and worrying about what they're going to do for the rest of their life. So fixed on trying to find the right living for fear of a miserable existence they feel they don't deserve and getting disappointed when they don't love every moment of the work they are in. I got tired of worrying and perhaps other people are tired too. Read this article. It's called "The Passion Trap".
The Passion Trap: How the Search for Your Life
Most people I have met built satisfying careers not by following some innate passion of theirs, but because they honed a craft and got really good at what they did. One of them I know works for the FAA as an airport safety inspector (that was just one of her position titles). You would think that's a boring job which is a far cry from being a flight instructor (her job before that), but she refuses to retire because she loves her work so much and is well-respected for her experience at the job.
Of course, these people chose a path they were interested in, but to be interested in an area is only half -- or less than half -- of the battle to building a satisfying career.
