I'm more interested on the second, as the first one seems just a consequence of being disciplined on first one but adding whatever else than code, but still producing / doing deep work, like any marketing related copywriting stuff, design, which is usually code anyways, etc...
I recently came upon lots of free time and I'm more and more inclined to do one side project, I don't think it will free me to need a 9to5 job in the meantime, but at least I can be productive without being bossed around and just do whatever I want with it.
Might as well try to launch something public instead of acummulating unused private repos on github, I mean they're free now (thx microsoft overlords) but still failures on forgotten drawers...
Sorry for my random rant, thanks for sharing your experience!
