Yeah, I like human company, but my tolerance of and active desire for alone time is much higher than a lot of people's, and I can imagine people--maybe you--who have the slider even further in that direction than I do.

I need a lot of time alone. It's been true my entire life, but it becomes even more true the worse physical or mental shape I'm in, and consequently my baseline for introversion jumped in 2006 and I feel I have been becoming steadily more hermitlike over the last three or four years.

ETA: And on the contrary, the better you are at things, I think the more people seek your company--or at least, they certainly don't ignore you harder.

I was misled by literature and all its solitary geniuses!
