Are you me? I feel the same way and im too far gone to pivot at this point in my life. I did basic, Vbasic, and C++ back in middle/high school and even got some AP compsci credits. Chose not to do programming because I (very incorrectly) thought if I did that I'd always be working for someone else...

I feel you. I was having a lot of success with music by high school so I went full-bore and threw everything else out. Found my way into the telecom industry to pay the bills and that went well. Now I feel stuck wondering how I got here and not sure how to get back.
I guess sometimes it's baby steps in the right direction. The further down a particular path you go the harder it is to leap across to another one. But small steps will eventually compound and add up. At least that's how I've been approaching it. I've been stuck behind a desk doing tax accounting for almost 2 decades. But over the past 5 years or so I've been slowly pivoting away with different initiatives. Some successes, many failures. But im starting to see the fruits of my labor. Slowly then suddenly as they say. It's a very slow grind since I need to keep my day job to support the family but in my spare time I do everything I can to build what I want to be doing instead.
