I'm supposed to be writing about charm. I can't do that right now. I'm not thinking about charm. I'm thinking about expertise. About picking a something, and becoming an expert at it, no matter what it is.
Then, once you're an expert at something, you should operate there. For instance, a business full of people operating at top capacity in their realm of expertise will be exponentially more successful than a group of people thrown together helter-skelter, willy-nilly.
Become an expert at something.
Then, do it!
