Never let another's opinion affect you; he cannot tell what you are able to do; he does not know what you can do with your forces. The truth is you do not know yourself until you put yourself to the test. Therefore, how can someone else know? Never let anyone else put a valuation on you.Almost all wonderful achievements have been accomplished after it had been "thoroughly" demonstrated that they were impossibilities. Once we understand the law, all things are possible. If they were impossibilities we could not conceive them.
Just the moment you allow someone to influence you against what you think is right, you lose that confidence in yourself that inspires courage and carries with it all the forces which courage creates. Just the moment you begin to swerve in your plan you begin to carry out another's thought and not your own. You become the directed and not the director. You forsake the courage and resolution of your own mind, and you therefore lack the very forces that you need to sustain and carry out your work. Instead of being self-reliant you become timid and this invites failure. When you permit yourself to be influenced from your plan by another, you are unable to judge as you should, because you have allowed another's influence to deprive you of your courage and determination without absorbing any of his in return so you are in much the same predicament, as you would be in if you turned over all your worldly possessions to another without getting "value received."
Concentrate on just the opposite of fear, want, poverty, sickness, etc. Never doubt your own ability. You have plenty, if you will just use it. A great many men are failures because they doubt their own capacity. Instead of building up strong mental forces which would be of the greatest use to them their fear thoughts tear them down. Fear paralyzes energy. It keeps us from attracting the forces that go to make up success. Fear is the worst enemy we have.
There are few people that really know that they can accomplish much. They desire the full extent of their powers, but alas, it is only occasionally that you find a man that is aware of the great possibilities within him. When you believe with all your mind and heart and soul that you can do something, you thereby develop the courage to steadily and confidently live up to that belief. You have now gone a long way towards accomplishing it. The chances are that there will be obstacles, big and little, in your way, but resolute courage will overcome them and nothing else will. Strong courage eliminates the injurious and opposing forces by summoning their masters, the yet stronger forces that will serve you.
Courage is yours for the asking. All you have to do is to believe in it, claim it and use it. To succeed in business believe that it will be successful, assert that it is successful, and work like a beaver to make it so. Difficulties soon melt away before the courageous. One man of courage can fire with his spirit a whole army of men, whether it be military or industrial, because courage, like cowardice, is contagious.
The man of courage overcomes the trials and temptations of life; he commands success; he renders sound judgment; he develops personal influence and a forceful character and often becomes the mentor of the community which he serves.
