Dopamine can be a great motivator, and even when it’s tempting us to order dessert or to run up credit card debt, it’s hard to describe this tiny neurotransmitter as evil. But dopamine does have a dark side — one that’s not hard to see if we pay close attention. If we pause and notice what’s really going on in our brains and bodies when we’re in that state of wanting, we will find that the promise of reward can be as stressful as it is delightful. Desire doesn’t always make us feel good; sometimes it makes us feel completely awful. The reason that dopamine’s primary function is to make us pursue happiness, not make us happy. It doesn’t mind putting a little pressure on us even if that means making us unhappy in the process.
