Quiet Revolution has an interesting profile on the life and personality of Steve Martin. Despite how he — and many other comedians — appears in character, he's a quiet introvert. It goes to show how far one will go when one who is serious about their craft. Doing the things he's done in front of an audience causes this introvert to cringe.

He was completely focused on working and learning to be a performer, and all his enjoyment seemed to be derived from making headway on those fronts. Interacting with his peers was mostly a distraction that he cheerfully tolerated between practicing magic, juggling, and playing banjo.

Friends were cheerfully tolerated. What a great way to put it! I imagine a lot of introverts might nod their heads when reading that. Friends are a blessing and human interaction a necessity to a good life … but in just the right amounts!
