I'm so called retired (no longer able to run a business but not yet stupid).
I liked all three of my careers, which were sort of interwoven.
First I worked as a lab tech and was lucky to connect to a uni department that was at the forefront of stuff. I quit that at one point because I was frustrated that I wasn't learning hematology, my main med interest. Snort - I had a good time at the next lab but it was no advancement. Fine memories though.
Applied to the uni re a job in hematology and got shunted to my old boss, who told me a pal was now out of the armed forces and setting up a hematology immunology lab. I listened, and had another set of excellent years as his main tech.
Got interested in art after work.
Got an inquiry to help so and so to set up a lab. (That lab is now Quest, she chuckles).
Did that, but didn't want to be a manager (who, me?)
Quit five years later, studied landscape architecture. My world widened, hard to describe how much. I'm not all land archy, but still have wider vision than I did to start with.
got licensed in that. Years of school starting at forty. (Don't whine to me).
In the middle of all that I took batches of studio art courses. Learned some stuff. Am a painter.
This is a tough time, crazie, but when I got a long time wonderful job with a local landarch, he was something like my ninetieth call. We're still talking all this time later.
I think you are creative, cl and haven't explored that.
