dopamine is a tool our brains use to form memories and record things that are worth doing again—in other words, it’s a salience indicator. Dopamine focuses our attention on the present moment, helping us to tune in to sensory details and experience things more intensely. This means that every time we rebel against our routines and habits and have an even slightly positive experience, not only will we be creating a vivid memory to look back on but the ensuing dopamine jolt will reinforce the idea that trying new things is worth repeating in general.
