Every advantage has an expiration date. Use it while it’s real, not after everyone’s caught on.

Advantages come from a gap, where you know something or can do something the people around you cannot yet. Gaps close. Others learn the thing, the tool gets cheap, the trick becomes standard, and what was an edge becomes the baseline everybody meets. Nothing goes wrong, and the clock simply runs.

Name the thing you are currently ahead on and ask how long that is likely to last. Then use it now rather than saving it. If the answer is that it is already closing, start building the next one while this one is still carrying you.
