Be considerate of other people's time. Make sure if you have an appointment with someone for an interview, a meeting, or just an appointment of any kind, that you show up or you let them know if you're not able to make it. Yesterday, I had an interview scheduled to interview someone and I spent 45 minutes preparing for the interview and the person never showed up and never called. It wasted my time that I could have been doing other things and been more productive. Being considerate of others is a character trait, that to me is important and a trait that I believe one should model the way for others.
