Make a list of your outcomes as a non-smoker, the positive benefits you will personally enjoy and appreciate.
Understand that you get nothing from smoking. If you'd never lit one you'd never want one and soon you will be back in that situation.
If you ever think about cigarettes, immediately repeat to yourself your personal affirmation, at the same time reminding yourself of all the wonderful gifts you are giving yourself.
Commit 100% to making this a permanent smoking cessation and notice the relief as you do.
Start to use your powerful imagination in the way described on page 30.
