Avoid certain people that may bother you. If there is a lot of tension at work, try to get a few days off. If you can't get some time off, quit smoking on a long weekend. Avoid, as best you can, things like getting stuck in traffic. Use a lot of caution.
Anger can be very destructive.
Don't get too hungry. It is amazing how our minds will tell us that everything's wrong when all we really need to do is eat. Don't get too tired. If we are tired, it is easy to become irritated and when we get irritated our minds will tell us that a cigarette will help. Don't get too lonely.
