In my case, I didn't expect to enjoy learning Paraguayan traditional dancing, but it sure was fun and I'm glad I tried it. Like another poster pointed out, it's the hard work that comes first (overcoming the fear, or plugging away at the books), then comes the satisfaction. I think it must feel lonely being a great mathematician for example, knowing that everyone else has settled for less, and that only you and a few others have even a slight understanding of the universe.
