Get angry at the fact that governments make billions from smoking tax and then spend a few million on scary adverts supposedly to make you stop. Get angry with tobacco companies for spending billions on highly effective marketing campaigns to start people smoking and to keep them smoking. Get angry about people saying you should be at the back of the cue for hospital treatment when your smoking tax has paid for that hospital. When you've finished being angry, just stop smoking, then you don't need to be angry any more.
These things won't concern you. You can just think about your positive and healthy future.
