Black Swan
In the context of trading once you know what you're doing it takes pretty much no energy. Depending on how you trade you could have long periods of free time, which you may or may not decide to use to teach. Your argument is that should you choose to teach. Which your enormous intellect has somehow deduced to mean that such a person must automatically be mediocre at what they do.
classic nub idea that trading takes active work whereas in practice once you know what you're doing often the more passive you become the better
Amen to that brother..
