Also about the pain vs. pleasure response. Ultimately, we as humans, are always trying to either obtain more pleasure or avoid some level of pain. This is true for every task and decision we make in life. If we take the task of going to the gym for instance, some people associate going to the gym with "pain". I.e. I don't want to run because I"m tired. Whereas others associate going to the gym with "I want to feel good and have more energy". The trick is being able to combine the power of habit (cue) with pain and pleasure. All of this can be read in Awaken the Giant Within by T. Robbins. Oldie but a goodie classic on this stuff.
