Exactly. Most of these read as "I went into a different specialization of the same field".

Where is the engineer that just chucked it all and opened a donut shop? That's the level I want to know about. Most of these are just stories of people making lateral moves in the same industry.

Sure. I do. I still haven't quite made it to first base with the new career but that's because I am solopreneuring and building the first platform. This takes time! However, I have come a long way.

My story doesn't feel unique. I learned what was necessary to then acquire skills used to create experiences by building lots of software every day for years. I gave back as I grew. This process continues today.

I've done this over and over, across disciplines. However, tech has captured my focus entirely for the time being.

Perhaps because the OP specifically asked for experiences not involving career changes?
