Here's why:
1- Rewards positively reinforce the behaviors you are trying to establish.
2- Rewards give you something to work towards. Resisting cravings will be easier if you are rewarded for overcoming temptation.
3- Rewards are motivational and make you happy.
Tips
1- Reward yourself for every craving you overcome and every situation/trigger that you've handled well, smoke free.
2- Choose rewards you value and are willing to work towards. Acquiring them must be important to you.
Hope this helps.
