I'm a high school choir director, and most days, I really like what I do, especially during the summer. There are times when the kids are around the piano and they're learning notes and we start putting different voice parts together and the kids hear themselves harmonizing and their eyes light up and it's really magical. Then the bell rings and they have to go do some math. I often have kids tell me that my choir was the main factor in them staying in school to graduate. That's "...such a good feeling...", as Mr. Rogers would say.
How did I get this gig? I applied for it. There was one Music Ed. job open in my county that year, and I was the one applicant, so, lo and behold, guess who got the job? Yours truly. Seven years later I'm still plowing away at it.

In the past I worked in a cultured marble plant. Didn't love that. I DJed 3 nights a week on the local AM station. It was OK for a little while, but it got old. I worked in a dept. store for a while. Didn't love that.
A college friend had been in the Coast Guard, and he said someone he knew on the ship would say, "Figure out what you are, and be that." That's the best career advice I can offer.
