I often give a similar list as a glib answer in interviews when asked "what are your greatest strengths?"
Mine are usually: I'm stupid (not smart enough to overcomplicate), lazy (prefer turning MVP in on time rather than adding too many bells and whistles), and forgetful (document everything because I won't remember what I was doing the next day).
Working too hard means you're liable to disappear for 6+months, no sane employer should want that!
But there were others as well. Burnout is complicated.
I will say tho, it gave me persistent back problems and RSI for two years :). But that again is not just “working hard”. It was bad posture, lack of stretching, breaks and exercise, I think.
Edit: Perhaps it’s the nature of the work or working hard unhealthily (physical and mental?) or the person’s characteristics.
Because this is that.
(I've worked (and interviewed) as a programmer at VC backed startups and FAANG in SF and NYC over the past 12 years)
