The only way to outperform if you’re doing undifferentiated work is to work harder than everyone else. - Shane Parrish

However, not every model is as reliable as gravity, and all models are flawed in some way.

Ideas are cheap. Execution is expensive. The ability to execute separates people, not the ability to come up with ideas.

It’s not just knowing the mental models that is important. First you must learn them, but then you must use them. Each decision presents an opportunity to comb through your repertoire and try one out, so you can also learn how to use them. This will slow you down at first, and you won’t always choose the right models, but you will get better and more efficient at using mental models as time progresses.
