Anywho-it's closer to 3.5 years now that I've done this, maybe I'll do an update at 4 years.
The 2.5 year initial duration (when I posted that article) was like working two full-time jobs, 100h/week, almost solely writing code.
Past year has been more like 85h/week, my dayjob has required more time (48h -> ~60h week), with much less of that time at work being /writing code/; and ~25h/week going to my gamedev passion projects, of which a good chunk has also gone to helping others with their code/issues.
The -15h/week 'loss' has gone to caring for pets, and a gentle touch more travel/sleep/gardening. Doing well and enjoying my life, still.
