The four fastest ways to make money have never changed:

1. Information Gap
What I know, you don't. The information gap is about earning benefits from information that is difficult to pass on during a boom.

2. Cognitive Gap
What I understand, you don't. There's a saying: cognition determines the upper limit, effort determines the lower limit.

3. Execution Gap
You and I both understand, but you don't do it, I do. Execution is the key to widening the gap between people.

4. Competition Gap
You and I both do it, but I do it better than you. When you perfect something to the extreme, it's already a success. True experts are not just capable, but do it better than others.
