My brother had a similar experience once and told me something that has stuck with me. “You’ve got to have a job or you get weird.”
My recent experience has colored my entire opinion of the thought of retiring early and retiring in general. I’m not sure I ever want that. Although I don’t want to lose 40+ hours of my life each week either. I think 3-4 days worth of work per week would be about perfect. Or working only mornings. Everything you actually need to do at work could probably be condensed down to each morning. The rest is filler and pointless meetings. But going to zero work hasn’t felt good either.
