You will only be deceiving yourself

From Napoleon Hill, The Law of Success

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 co-operation of other people. Success is a matter of individual effort only to the extent that each person must decide, in his or her own mind, what is wanted. This involves the use of "imagination." From this point on, achieving success is a matter of skillfully and tactfully inducing others to cooperate.
