A person who doubts himself is like a man who would enlist in the ranks of his enemies and bear arms agains himself. He makes his failure certain by himself being the first person to be convinced of it.
The key to realizing a dream is to focus not on success but significance - and then even the small steps and little victories along your path will take on greater meaning.
