Breadth as well as deliberate practice

David Epstein in an essay based on his book suggests that late specialisation is useful and that the narrative of only 10,000 hours deliberate practice is not the only path to happiness and success.

Practice is still needed though. It chimes with being a “fox” over a “hedgehog”.

This is also useful in super-forecasting.

“Over time, as I delved further into studies about learning and specialisation, I came across more and more evidence that it takes time to develop personal and professional range – and that there are benefits to doing so. I discovered research showing that highly credentialed experts can become so narrow-minded that they actually get worse with experience, even while becoming more confident (a dangerous combination). And I was stunned when cognitive psychologists I spoke with led me to an enormous and too-often ignored body of work demonstrating that learning itself is best done slowly to accumulate lasting knowledge, even when that means performing poorly on tests of immediate progress. That is, the most effective learning looks inefficient – it looks like falling behind.”
