Because men know that the conquest of one's own weaknesses is a far, far more difficult task than any other, they tend to believe that he who can conquer himself, can also conquer whatever problem is at hand.
Your first job, then, is to learn to know your own weaknesses and conquer them. Our fears are a key to our weakness, because we fear only the things which we feel we cannot do well. We all have fears. Force yourself to conquer and to face squarely every situation you are afraid to meet. It is not being afraid but running away that weakens character. When you have accomplished this, you will have developed character.
