> Have worked with a lot of very unhappy geniuses.

I haven't worked with a lot of very obvious geniuses, strictly speaking, but I've known plenty of very smart people who weren't particularly happy. And I've known several people that I absolutely would not consider geniuses who were nevertheless brimming with curiosity, successful, and quite outwardly cheerful (though at least one suffered from anxiety and depression).

Heck, going by IQ I'm only, what, 15 points off from genius and I'm not particularly happy either. Nor am I that smart for values of "smart" that people would traditionally associate with genius, but maybe that makes all the difference? I can barely do tips in my head ...

Multiply by .10 by moving the decimal on the bill. So 15.23 would be 1.523 and then just double it - 3.0 for a 20% tip.

All the genius-level people over had the pleasure to work with had tremendous amounts of curiosity on common. They were having a lot of fun when they got to explore something new. I do know though that several of them also struggled with depression at the same time.

> But maybe they do perform well.

More likely it's "well enough", and that matches the needs of most organizations just fine.

I would expect that corporate logic will then simply dictate happiness. Wasn't there a case in China or Japan were employees must smile to open doors? They are probably extremely happy employees.
