Do you ever wish you could just turn on the happy chemicals in your brain? Imagine how much easier it would make getting out of bed each morning, getting even the most tedious parts of your job done, and finding the energy to consistently show up as your best self for the people you care about the most. But is it really possible – never mind advisable – to try and train our brains for more happiness?

“The quest for good feelings is nature’s survival engine,” explained Professor Loretta Breuning, founder of the Inner Mammal Institute, when I interviewed her recently. “For example, animals seek food to relieve the bad feeling of hunger. They seek warmth to relieve the bad feeling of cold. And happy chemicals start flowing before a mammal even eats or warms up because the brain turns them on as soon as it sees a way to meet a need.”
