"Any behavior that gives you temporary relief/ pleasure which causes consequences, but you cant give it up"

Some peoples' brain are more susceptible to liking dopamine (the chemical that is produced after most substances are induced)?
How?
What has happened to these peoples brains (in childhood)?

It is imperative to look at the past environmental factors to understand this: stress, abuse, neglect, emptiness, loss, trauma... brings about the "hook" of dopamine.

People in power often are empty, traumatised, lost. Why do we follow them?

Having the power (the light/ insight) inside oneself is the solution to change, not relying on others who are in power.
