You should really watch that video, it goes into great details, backed by scientific research, into how and when the 10,000 hours trope works and where it fails

You should really watch that video, it goes into great details, backed by scientific research, into how and when the 10,000 hours trope works and where it fails. Creativity and skill are somewhat orthogonal, you can be an exceptionally well read and educated person yet never publish anything. But it's extremely unlikely you will create anything out of thin air without good technical skills. We like to to obsess about outliers like Beethoven, the deaf composer, but in reality the vast majority of famous musicians are recruited from accomplished instrumentalists.
