Substance is style!
All the fashion sense in the world won't help you if you have nothing interesting to say. You should make sure you read good books outside your specialty, listen to quality music, and enjoy some cinema (not just "movies") once in a while.
Here are some picks in each category from amazon.com.
- Book: Guns, Germs, and Steel by Jared Diamond. It won the Pulitzer Prize for a good reason, folks. Hardcover ($18.87) or paperback ($11.02).
- Music: Eye to the Telescope by KT Tunstall. Strong, mellow, original songs with great lyrical imagery. The audio CD is only $9.76.
- Film: 12 Angry Men, directed by Signey Lumet. This is a tense drama aout a jury trying to determine a verdict in a murder trial. Absolutely classic, and a great film to watch with friends. On DVD for $9.99.
