Who never doubted never half believed,
Where doubt, there truth is - 'tis her shadow. [ Bailey ]

It is to be doubted whether he will ever find the way to heaven who desires to go thither alone. [ Feltham ]

Of many imagined blessings it may be doubted whether he that wants or possesses them had more reason to be satisfied with his lot. [ Dr. Johnson ]

The man who makes a success of an important venture never waits for the crowd. He strikes out for himself. It takes nerve, it takes a great lot of grit; but the man that succeeds has both. Anyone can fail. The public admires the man who has enough confidence in himself to take a chance. These chances are the main things after all. The man who tries to succeed must expect to be criticised. Nothing important was ever done but the greater number consulted previously doubted the possibility. Success is the accomplishment of that which most people think can't be done. [ C. V. White ]
