Nine sources of advantage
Raw talent/intelligence - Some people are just naturally better and smarter.
Hard work - Some people work harder.
Differentiation - Seeing the world differently. Doing something different. Reading different books. Interpreting the same information differently.
Process / Discipline - Creating a process and following it. Working out every day is a great example.
Talent Collector - The ability to hire the best people and get the most out of them.
Patience - A lack of patience changes the outcome.
Ability to take pain - Are you willing to look like an idiot to get better? How much risk are you willing to take, AND, importantly, can you handle the losses?
Temperament - Keeping your head when everyone else is losing theirs.
