For me its about anxiety, and that ability to drudge on. Certain parts of my brain fatigue and completely turn off. After an all-nighter my emotional resilience is off the charts the next day. I think a little slower, but so much more calmly, and logically. At my startup my co-founders actually requested I pull all-nighters before pitching VC's because the effect was so profound. Public speaking is so easy when you stop caring and treat everything like an item on a checklist instead of a potential catastrophe.
