In fact, I suspect almost nobody is that self-optimized. We do things like neurofeedback because (1) we don't think enough about choosing the highest-leverage self-interventions, (2) in any case, we don't know how to figure out which interventions would be higher leverage for ourselves, (3) even if there are higher-leverage interventions to be had, we might not successfully carry them through, but neurofeedback or whatever happens to be fun and engaging for us, and (3) sometimes, you gotta stop analyzing your situation and just do some stuff that looks like it might help.

(5) Neurofeedback is fun. I certainly wouldn't do it because I thought it was the single most effective thing I could possibly do that second. But I like doing fun things sometimes.

[One of those (3)s should be a (4).]
