Kurt Vonnegut on Creating
You know what they say about singing like no one's listening... One of the key ways to develop creative confidence and live a creative life is to get in the habit of creating. Like anything else, creating and seeing yourself as a creative person takes practice, and the more you do it, the easier it gets.
So, summon your powers of ignorant bliss and find an outlet and find an outlet to express your creative self. Better yet, find three and try them all, especially if they're out of your comfort zone. Remember, you'll have "created something" -- and something is more than nothing.
