I was in denial about this for a long time, but the fact of the matter is that your overall outcome is almost entirely determined by your outliers. If you take all of the investments I've ever made, including going to work as an early hire at Google, the I've won. If I leave out Google, then I've lost. If I leave out my single biggest loss, then I've won again. If I leave out my next biggest win, then I've broken even.
