Liking is the pleasure you experience from something. The source of that pleasure is the liking—or Here and Now—neurochemicals released in your brain: serotonin, oxytocin, endorphins and other endogenous opioids, and endocannabinoids. The same pleasure-generating areas in the brain are activated for all pleasures, from gustatory and sensual to musical, artistic, and altruistic.
Life’s intense pleasures are less frequent and less sustained than intense desires. —Dr. Kent Berridge, University of Michigan
Because the pleasure circuit is considerably smaller and far more fragile than the “wanting system,” it can be elusive; more importantly, it is always transient. Liking something doesn’t always motivate you to go after it. Dopamine is what generates motivation, so you also need to want what you like.
We often think of desire and the objects of our desire as inseparable. We think it is the indulgence itself—the luscious ice cream, the rush of nicotine, or the flood of coins from a slot machine—that motivates us. To a greater extent, however, it is the expectation of these rewards, the luxurious anticipation of them, that fires up our brains and compels us to dig in, take a drag, or place another bet. —Chris Berdik, Mind over Mind
While liking (pleasure) and wanting (desire) are separate systems, wanting actually enhances and, in a sense, prolongs liking. It’s said that the brain likes to want because it releases liking neurochemicals along with dopamine. On the other hand, instant gratification quickly dissipates pleasure. That’s how you end up on the hedonic treadmill where you are continually in pursuit of more and more of the things or experiences that initially brought you pleasure in an attempt to maintain a steady state of pleasant feelings.
When you work toward a reward and earn it, rather than simply treating yourself to it because you can, you actually enhance your enjoyment of it. But you have to be intentional about it. You have to make a connection between your actions and the reward so your brain gets the message.
Dopamine is a powerful motivator. It carries signals for both rewards and for the muscle movements needed to go out and get them. So when dopamine levels are diminished, you will still like what you like, but you will be less inclined to take action to get it. And when dopamine levels are elevated, you will be more inclined to take action to get something, whether or not you actually like it.
Liking and wanting usually do work together in your brain, but when they become uncoupled, you can want something without liking it. And according to Stanford University researchers, if you don’t get something you want, you desire it more while liking it less.
If you don’t clearly identify what you want—and determine how you’re going to get it—you’re liable to end up going along for the ride of getting what your brain wants. What you want needs to be compelling enough to you to activate the amygdala, thus creating a sense of urgency. Amygdala activation is critical in getting you to act on your desires. It settles down when you receive or achieve them.
In the case of long-term goals, once you’ve identified a reward and begin taking steps toward it, your brain gradually and steadily releases increasing bursts of dopamine the closer you get to the reward. And the bigger the reward (the more your brain craves it), the more dopamine will be released.
Reward systems integrate liking, wanting, and learning. Our pleasures help us learn and change our behavior, and what we learn alters the pleasure we experience. Our reward system has a built-in flexibility in which cognitive and pleasure systems interact and modulate each other. Anything can be a source of pleasure as long as it taps into reward systems embedded in our brains. –Anjan Chaterjee, author of The Aesthetic Brain
Wanting has a purpose. It is critical to any focused effort. It motivates you to pursue both long-term and short-term goals. But, as Chris Berdick says, once that goal’s been achieved, wanting moves along.
Unsurprisingly, liking neurochemicals have a close relationship with stress neurochemicals—adrenaline, norepinephrine, cortisol, etc.—which I also call disliking neurochemicals. I’ll talk about how that relationship can hamper our ability to create change next time.
