Just to help with feedback, I'm one of those who retired before 30s. Not rich but enough savings to live on a (humble) tropical island until old age.

I wasn't able to stop. Applied my savings in day trading, everything went well until 2009 happened and most of it washed away. Applied what remained on the tuition of a top university to up my academic credentials and then went on try other tech industries (e.g. aerospace). Today have a small startup (Europe). Life is hard (empty bank account at the end of the month) but the plus side is that your brain keeps active.

If you really like writing technology, in my opinion it gets difficult to stop doing what you naturally enjoy doing.
