Norman Vincent Peale
There is a real magic in enthusiasm. It spells the difference between mediocrity and accomplishment.
It's always too early to quit.
The trouble with most of us is that we would rather be ruined by praise than saved by criticism.
Four things for success: work and pray, think and believe.
Watch your manner of speech if you wish to develop a peaceful state of mind. Start each day by affirming peaceful, contented and happy attitudes and your days will tend to be pleasant and successful.
Believe in yourself! Have faith in your abilities! Without a humble but reasonable confidence in your own powers you cannot be successful or happy.
Change your thoughts and you change your world.
