1.) Other people. I love to ask people what they are reading including magazines, newspapers, websites, books and articles. Usually what they share has touched them and made an impression, and worth noting. In my Palm under tasks, I have categories in which I enter books, magazines, websites and news to check out the next time I'm at the library, bookstore or on the Internet.
2.) The library. I visit our local library about twice a month. Great source for books, books on CD and cassette and books on MP3 players.
3.) iTunes podcasts. Incredible resource to play while on the go and in place of the radio talking heads. You can also download audio books.
4.) CBS Sunday Morning, Public Television and The Discovery Channel. I do not watch much television, but I tend to be intentional in watching these (as well as ESPN!) These help justify the cable bill!
5.) Websites I frequent.
