I believed this, which is what made me avoid computer science in college; I wanted to avoid ruining my favorite hobby.
After a few years post graduation, where I wasn't sure what I wanted to do and I floundered to find a career, I decided to give software development a try, and risk ruining my favorite hobby.
Definitely the best decision I could have made. Now people pay me a lot of money to do the thing I love to do the most... what's not to love? 20 years later, it I still my favorite hobby, and they keep paying me to do it.
I think it heavily depends on who you're working for.
If they get out of the way and let you do the thing you love how you want to do it you'll get good results for you and them.
If they treat you like a cog in a machine and assume they need to carrot and stick you into doing things because you might not really want to be there, you'll be miserable.
Sure, of course. Sometimes it works out to follow your passion into a career. I was objecting to the apparent premise that that’s _always_ what you should do.
My first software job I enjoyed. My 2nd/current job I enjoy everything except the actual work. Too much beuracracy, but it hasn't ruined my love for the craft yet. Oh well, I'm building some other skills I didn't know I had in me.
What you do at work today doesn't mean you can't switch to a related ladder.
