"But if you want something extraordinary, you have two paths:
1. Become the best at one specific thing.
2. Become very good (top 25%) at two or more things.
The first strategy is difficult to the point of near impossibility. Few people will ever play in the NBA or make a platinum album. I don’t recommend anyone even try.
The second strategy is fairly easy. Everyone has at least a few areas in which they could be in the top 25% with some effort."
