"I never made lots of money at it, but I sold enough"

Jack Vance's quote speaks with the idea of success and how it is measured. He is saying that although he did not make a lot of cash from whatever he was doing, he was still effective because he sold enough. This suggests that success is not always measured in financial terms, however rather in the satisfaction of attaining an objective. It implies that even if one does not make a great deal of money, they can still succeed if they have the ability to reach their goals. This quote is a reminder that success is not always determined in financial terms, which it is possible to be successful without making a great deal of money. It is a pointer that success is relative which it is possible to be effective even if one does not make a great deal of cash.
