> Exercise, for example, is bullshit make-work that only some subset of people are wired to enjoy for some reason (never worked out how, I'm gonna guess they're either wired to receive reward signal for this, or it's social activity; half of life's motivation is low-key sexual drive anyway). I don't. So I have to find whatever proxy that works for me.

I honestly think nobody enjoys the exercise itself. The real motivation is second order effects like becoming more appealing to other people.
