The great creators - the thinkers, the artists, the scientists, the inventors - stood alone against the men of their time. Every great new thought was opposed. Every great new invention was denounced. The first motor was considered foolish. The airplane was considered impossible... But the men of unborrowed vision went ahead. They fought, they suffered and they paid. But they won.
