Maybe. Focusing on one skill by definition limits your ability to master other skills due to time requirements. Most things take thousands of hours to get great at, and 10,000 hours is a common hourly figure that's thrown around (from the book Outliers), but several studies have suggested that number isn't real at all. One thing that's true is that anything can become an unhealthy addictionIt;s great to have passions, or even lose yourself in them, but not to the point where it's unhealthy.
I was planning to ask Josh Waitzkin about this. He's the kid from the movie (not the actor, but the actual chess player.) He's grown up now and helps run the academy of the best submission grappler/Brazilian Jiu Jitsu athlete ever, Marcelo Garcia. If he was up there when I visited, I was planning on asking him if a chance opened up. Why he stopped chess, but stayed in similar fields, etc.
Waitzkin doesn't play as much chess anymore, and is into grappling/Jiu-Jitsu, and has some other interests as well. I know he's not Bobby, but he had a singular drive in much the same way. I think it's interesting that his current pursuits are still very similar and cerebral.
I have so many interests that sometimes I'm frustrated that I only have one life to pick from them, because i know I can't realistically dive into everything the way that I'd like to.
