A question I love to ask people is, “What have you changed your mind about in the last decade?” I use “decade” because it pushes you into thinking about big things, not who you think will win the Super Bowl. I am always so suspicious of people who say, “nothing.” They act like it’s a sign of intelligence – that their beliefs are so accurate that they couldn’t possibly need to change. But I think it’s the surest sign of ignorance and stubbornness.

It might sound crazy, but I think a good rule of thumb is that your strongest convictions have the highest chance of being wrong or incomplete, if only because they are the hardest beliefs to challenge, update, and abandon when necessary.

Be careful what beliefs you let become part of your identity.

Most fields have lots of rules, theories, ideas, and hunches. But laws – things that are unimpeachable and cannot ever change – are extremely rare.
