Often, when I'm contacted by someone that I haven't talked with in a long time, they will ask me whether I still play guitar or whether I've been riding lately. Thinking about it this morning, I realized that there are a bunch of things like guitar that I probably have 9,998 hours at.
Perhaps you know the feeling. One day, when I get some time, I will devote some more time to it, focus on it, and finally cross that expertise finish line. Hell, if it were just one hour a way, I'd probably pull out that guitar right now. But it's not just an hour. It's not just one more turn to level up. So I should probably focus on something else. Besides, that next hour will probably be awkward.
