There's a legend that the violinist Giuseppe Tartini kept himself in a room to practice almost constantly for years. When he reconnected with the world, it's said that it was hard to believe how much better he had become. If you could lock yourself in a room for a year to practice a single skill with zero social or economic repercussions, would you do it and what skill would you choose? Here's the rules: All of your living expenses are paid for, but you can't leave your room for any reason other than to use the bathroom, you can't opt out once you start, you cannot have access to any form of entertainment other than, you must spend as much time as possible practicing.
