Some Things I’m Pretty Sure About

I increasingly don’t believe in gurus, in any field. Everyone puts their pants on one leg at a time and is susceptible to the same derailing faults as everyone else.

Innovation and economics can be miles apart. Twitter directly influences geopolitics between nuclear states and is worth half as much as Progressive Auto Insurance.

Investing is one of the simplest fields run by people who believe in their souls that they’ll do better if they make it more complicated.

Few superpowers are as super as the ability to change your mind. It is so much easier to fool yourself into believing a falsehood than admit a mistake.
