Consider the attitude of a child who’s learning to walk. When he stumbles and falls down, what does he do? I’ll tell you what he doesn’t do. He doesn’t frown or blame the carpet. He doesn’t point fingers at his mother or father for giving him lousy instructions. He doesn’t quit. Oh, no. He smiles, gets up again and makes another attempt. And another. He keeps going for weeks and weeks with a positive attitude until he gets it right! His window is squeaky clean, and he feels like he can conquer the world.
