From the Weight Watchers "The Quick Start Plus Program" pamphlet for week 2 (Weight Watchers International, 1985):

You're off to a great start -- now keep the ball rolling? How? Rehearse these phrases to yourself:

• "I like myself."
• "I want to succeed."
• "I can succeed."
• "I will succeed."

And believe what you are saying, because once you do that -- success is yours.
