Do continue to believe that with your feeling and your work you are taking part in the greatest; the more strongly you cultivate in yourself this belief, the more will reality and the world go forth from it.
Many of the most successful men I have known have never grown up. They have retained bubbling-over boyishness. They have relished wit, they have indulged in humor. They have not allowed "dignity" to depress them into moroseness. Youthfulness of spirit is the twin brother of optimism, and optimism is the stuff of which American business success is fashioned. Resist growing up!
