There is no such thing as a "self-made" man. We are made up of thousands of others. Everyone who has ever done a kind deed for us, or spoken one word of encouragement to us, has entered into the make-up of our character and of our thoughts, as well as our success.
Encouragement is oxygen to the soul. Good work can never be expected from a worker without encouragement. No one ever climbed spiritual heights without it. No one ever lived without it.
