“You be Simon. You’ve got something no one else has.”
Somebody will always be better than you at most things. You can get really good at a lot of things, but you can only be the best at one. There’s really only one thing you can definitively and consistently beat somebody at. Being you. You have your own unique strengths and weaknesses. Nobody else has the set of experiences, mindsets and abilities that have shaped you as you are.
If you position yourself well, you can be unsurpassed. A specific combination of actions will put you in the most advantageous position you can possibly create.
Find it. Do it. Hone it. Ignore everything else.
