“Wherever you are, whoever you are, whatever you may be following as an occupation, there is room for you to make yourself more useful, and in that matter more productive, by developing and using your imagination. Success in this world is always a matter of individual effort, yet you will only be deceiving yourself if you believe that you can succeed without the cooperation of other people….
Before you can secure cooperation from others; nay, before you have the right to ask for or expect cooperation from other people, you must first show a willingness to cooperate with them. For this reason, THE HABIT OF DOING MORE THAN PAID FOR is one which should have your serious and thoughtful attention. This would, of itself, practically insure success to all who practice it in all they do.”
I excerpted here to give you the most value in the fewest words.
