I get emails: ‘I have a correction for you. I think you meant ‘underpromise.’ No, underpromising is lying. Don’t lie to your customers. Don’t lie to anyone. If I say I can get the job done in twenty days but I know I can do it in five, then I say five and deliver it in four. First off, everyone else is lying and saying twenty. You win the job by saying the truth (five). And you push yourself and challenge yourself to do it in four. You become a better person. The client is with you for life. And you exercise the muscle that pushes you to exceed your own expectations. Otherwise, you’re mediocre like everyone else. Don’t be mediocre.
