>Many subjects cannot really be learned from books. Regardless of how many history books you may read, for example, it will not shed the same insight as a profound discussion with a highly-experienced academic in the field. This is true for many aspects of the humanities.

Also, if you're really interested in a subject, talking with an expert is fun. You're really missing out on the good stuff if you keep to yourself and your books. I think this goes equally for the arts and the sciences.
