Dependability is a VERY important word! Always keep in mind that if you make an appointment with someone or give a deadline for a project that you should always produce what you promise. Don't get me wrong, things happen. If you can not keep the time you gave be considerate and let the other person know. Just not showing up or not completeing a tasks can and will put your name in a bad place.
I have said this to say always be considerate of others time and business!!
