The art of contentment is the recognition that the most satisfying and the most dependably refreshing experiences of life lie not in great things but in little. The rarity of happiness among those who achieved much is evidence that achievement is not in itself the assurance of a happy life. The great, like the humble, may have to find their satisfaction in the same plain things.
My mother drew a distinction between achievement and success. She said that achievement is the knowledge that you have studied and worked hard and done the best that is in you. Success is being praised by others. That is nice but not as important or satisfying. Always aim for achievement and forget about success.
Our achievements speak for themselves. What we have to keep track of are our failures, discouragements and doubts. We tend to forget the past difficulties, the many false starts, and the painful groping. We see our past achievements as the end results of a clean forward thrust, and our present difficulties as signs of decline and decay.
