Not only must you be an artist, must you be generous, and must you be able to see where you can help but you must also be aware. Aware of where your skills are welcomed.
Listen to your fear but don't obey it.

Popular is not the same important, or often, not the same as good.
Your history of work is as important as the work you'll do tomorrow.
Anticipated, personal, and relevant advertising always does better than unsolicited junk.
