I then also learned that writing down is useful for many other reasons. I will blog about them in a future post.
Now back to dopamine. Almost certainly every human being can recall that strong feeling of unbearable expectation to eat/drink/smoke/do something they "like" (or can't live without). We have even coined a word - "crave" and the way we see it - it is almost impossible to make any other choice than to go for it. Does this sound familiar? If it seems about right then you might be interested in what follows
When we chase something attractive dopamine is released in our brain. Dopamine is a neuro chemical which is absorbed by the brain areas responsible for attention, action, desire and (as recent research shows) reward. Various scientists (including Marc Lewis, PhD) have arrived at the conclusion that we can become addicted to the dopamine release.
If we become addicted to something (e.g. drugs, alcohol, cigarettes, etc) soon the release of dopamine is controlled by the anticipation of getting more. This is the strong feeling I mentioned at the start. And the more times we go through this process the stronger the feeling gets.
Another important details is that the decision to choose short term rewards is processed by one part of our brain (some call it the reptile brain, others the chimp brain) and considering the long term reward by another (the human brain). This is why we can get a feeling that we're having an internal battle or at least hesitating when having to make a decision what to choose.
And here's an useful tip: Decide to go for it but in 10 minutes. What happens is in a few minutes your human brain takes over and you are much more likely to make the correct decision according to your long-term goals.
Apart from learning a little bit more about how our brain works I've found the "Yes, In 10 minutes" suggestion to be quite useful - so why not try it yourself and let me know how it goes?
