Are You Rewarding Yourself 85% of the Time?

The dopamine system isn't purely this, this sort of interaction with the environment that's unmediated by you as an individual. It's highly, highly mediated by you as the individual to the point where the individual is largely deciding what it's going to reward and what he or she is going to reward themselves for. So we're born with billions of neurons, but no connections between them, almost no. And those connections build very quickly when you are under age seven. That's the missing link that we need to talk about.
