Don't kid yourself. A habit is something you do alot but could change if you had too. Smoking is not a habit, it is an addiction. The addiction has most likely wiggled its way into the centre of your life to the point that you associate most of your life and identity to it. Nicotine can subconsciously link itself to everything like an associational virus - the telephone, computer work, meals, driving, talking, walking, stress, joy, concentration, boredom, romance. Do you really think that all these things rely on tobacco? Perhaps you just have a habit of giving much more than your income tax to the Government, maybe just a habit of slowly destroying your body. Why not make a habit of trying to improve your health, finances, outlook and life by taking control of your habits?
