This is what I imagine addiction is like.
Say, you’ve given up beer. You find yourself walking to an event, and you see this bar/cafe that serves the “coldest beer ever”. The words trigger memories, stimulating a part of your brain to release dopamine. For reasons still unclear, the same neurotransmitter that played an important role in encoding those memories now helps bring those memories back and the pleasure associated with them; neural connections to other parts of the brain motivate you to act. The motivation can be so strong as to blind even common sense. You walk in.
Dopamine is part of a reward system involving neurons releasing it and responding to it and neural circuits around this. The process is physical and can be broken down. Briefly, the system is this: “stimulus –> motivation –> behavior”. Let’s call this the reward axis. This process can be interrupted. One can avoid the stimulus, or failing that, can associate a different motivation.
For instance, the sight of a beer bottle motivates one to look for it and then to drink it. To cut a drinking habit, one can train oneself to associate a beer bottle with thoughts of one’s damaged liver. Associating the ideas is itself a habit and building it might fail. Thus, withdrawal symptoms make it harder to kick certain addictions.
What’s interesting aside from addiction is how the reward system affects our view of reality. Constant activation of the reward axis leads to a habit. A habit allows the actor to move on “automatic pilot” for many small decisions, freeing his mind him for more important decisions. But even these small decisions become a signature and contribute to defining his character. Character in a way defines “laws” as to how a life is lived.
An interesting implication of “how a life is lived” is that to achieve your bigger dreams focus on the small actions. My favorite example: if you want to be rich, make it a habit to wake up at 5:00 a.m. everyday. Among other habits suggested from various writers I include:
- Speak louder. Inflect downwards at the end of sentences.
- Do not rush to respond, nod, and react to what people say.
- Show genuine interest in others. Mirror their actions.
- Control your breathing. This calms neural activity and emotion, freeing you to think more rationally.
- Be mindful. Feel your breathing, your toes, ambient sounds when you’re distracted.
- Exercise.
