“Otherwise, my top recommendation for talent development in any endeavor is usually the same: market the activity more widely and diversify the entry and development pipelines such that you give a chance to as many people with as many different trajectories as possible. I think when we push early selection and specialization, especially in sports, we do the opposite of that. We allow only kids with a narrow developmental trajectory and timing to make it. So you are essentially de-selecting people before they even have a chance to develop.” —science writer David Epstein, lifted from here
