The wise man sees the problem coming and adjusts. When you can do this with your clients, you provide a valuable service that they’ll never even know about. They’ll just know that working with you is awesome. You don’t wait until after the project to fix the problem.
If you’re tempted to wait until a complaint happens or a problem arises you still have to fix the problem, but stress is now involved and you look less competent.
If you behave like there is no second chance to fix something, you’ll get it right far more often.
As the old saying goes, if you don’t think you have the time to do it right, what makes you think you’ll have the time to do it twice?
Anticipating problems that may arise, or anticipating what you’ll be asked to do next and being prepared and ready to deliver instantly will be unforgettable–even if the clients(or your boss) have no idea how you are always so well prepared.
