What does it take to succeed?

A sales manager was once asked what type of salesperson he most needed. Here was his reply:

We need men of character. A salesman works again and again among the same class of people. Now in order to win success he must have a good reputation. We want men who find pleasure in their work. What has made some men great painters or great inventors, or great explorers? The pleasure they found in their work. No man ever succeeded who did not find real joy and pleasure in his work. We want men who will make their work the supreme delight of their life. We want men who put aside all that mars their success. There are some men who spoil their chances by some fault which they will not drop. We want men who will work up to their full capacity. Most men have greater capacity than they ever use. We want men who will take pains to understand their work.
