My 2 cents: 3. Habits are often formed because of/to adapt the environment. (evolution?) Hang out with smoker friends all the time, higher chance of becoming a smoker. Or if you have a door that doesn't shut/lock properly. It could lead you to form a habit of double checking the door every time you close it. Fixing the door would probably cause you to lose that habit. 6. A lot of behaviors are set off by certain triggers. It could be different for everyone. Smoker trying to quit should probably avoid being at places where everyone is smoking. AA member probably should avoid going to bars. Recognizing triggers allow you to avoid things that lead to undesired compulsive behaviors. At the same time they can be used to create desirable ones. Perhaps listening to motivational music or phrases will trigger someone to study and seek self improvement.
