The big things that come our way are seldom the result of long thought or careful planning, but rather they are the fruit of seed planted in the daily routine of our work.
Once you have sold a customer, make sure he is satisfied with your goods. Stay with him until the goods are used up or worn out. Your product may be of such long life that you will never sell him again, but he will sell you and your product to his friends.
