Be a person who stands by his or her word. Let your yes be yes and your no be no. Take care not to promise something which you may not be able to do; but if you do, then keep your word. Such people are rare but they have no problem finding respect from others and they walk through life with a clear conscience. But let your communication be, Yea, yea; Nay, nay: for whatsoever is more than these cometh of evil. Matthew 5:37
