I think some people spend all their time trying to get discovered for what they do. One day their efforts pay off and they do get discovered. But then they realize they have to keep doing what they do and they can’t keep up because they haven’t spent their energies practicing the skills that are required to perform consistently at a high-level. So they have a one-hit wonder and then get left in the dust.
This applies to a lot of things. I think of it mostly in the context of an artist producing art. It also applies to a businesswoman trying to get a promotion. She spends all her energies playing politics and trying to get the promotion. When she finally gets it she realizes she has to keep doing the same job, just with more responsibility. It also applies to dating. A guy spends all his energies trying to find a perfect partner. When he finally does find someone, he realizes that he has to rise to the standards of a perfect partner.
Don’t waste your time on marketing before the product is ready. Just do what you do, and keep on doing it.
