You cannot enjoy outstanding success in life without power, and you can never enjoy power without sufficient personality to influence other people to cooperate with you in a spirit of harmony. 
Napoleon Hill said that power comes from a pleasing personality that commands cooperation from others.  The knowledge of how to instill confidence in yourself from others is worth learning.  Napoleon felt that Henry Ford was one of the most intelligent men ever.  He may have been correct.  In 1927, it was said that Henry Ford received advance orders, with cash payments, for more than 375,000 cars. At an estimated price of $600.00 per car this would amount to $225,000,000.00 which he received before a single car was delivered. That is a definite demonstration of the power of confidence in Ford’s ability.
Napoleon believed that the success of Ford, Edison and Firestone resulted from a bond of harmony, which caused their minds to become blended into a “Master Mind” which is the real source of the power of each.  

There can be no development of a “Master Mind” where this element of PERFECT HARMONY does not exist. The individual units of the mind will not blend with the individual units of another mind UNTIL THE TWO MINDS HAVE BEEN AROUSED AND WARMED, AS IT WERE, WITH A SPIRIT OF PERFECT HARMONY OF PURPOSE. The moment two minds begin to take divergent roads of interest the individual units of each mind separate, and the third element, known as a “MASTER MIND,” which grew out of the friendly or harmonious alliance, will disintegrate. (Napoleon Hill)

As Solopreneurs, we tend to attempt everything on our own.  Wanting to be in charge do things ourselves—be independent and in doing so we cheat ourselves of the power of the coming together of two or more minds.  I would encourage you to find up to six others to meet with consistently to help each other achieve success.
