A fatal flaw in the "be really hard on yourself as the mechanism to achieve" plan is that even when you achieve you absolutely cannot believe it, because you've really overtrained being hard on yourself. You see a systematic undervaluing that robs you of true information about your work.

So, one of the hallmarks of maladaptive high achievement I look for, as a psychologist studying productivity, is inability to really celebrate.

@grimalkina I have definitely felt this. When I was at Facebook the performance review system was always very clearly: if you haven't maintained levels of achievement that would be redefining at other companies, you will be punished and put on a path to firing. The actual assessment process is pretty much whether what you did happens to be something that matches what the managers in the room have been thinking about.
