When we engage in behaviors that trigger the release of these chemicals, we feel good, and our brains learn to repeat those behaviors. Dopamine is a brain chemical that motivates us to seek rewards. When we anticipate a reward, dopamine is released, making us feel good and motivating us to pursue the reward.
