1. Dear women of the world: don’t become a doctor. It literally isn’t worth the money.
2. Dear managers of the world: use your time wisely.
3. Dear self: read Peter Thiel’s class notes a few more times and think about them.
Quick comments on #2:
Companies live and die by their managers’ productivity. Some managers work insane hours and are willing to sacrifice every other aspect of their lives. These are more productive in an absolute sense. They waste lots of time, too, but eventually get to what’s important.
Some managers have uncommon insight into what problems their companies should solve and so get through the same amount of work with less wasted time. This, by the way, probably infuriates subordinates with a less clear understanding of corporate mission: their pet priorities get short shrift.
The rest fail.
