Habits of a
Happy BrainRetrain your brain to boost your serotonin, dopamine, oxytocin
Your happy chemicals are meant to do a job, not to be on all the time. When you know what they do in the state of nature, your ups and downs make sense. You can turn on your happy chemicals in new and natural ways when you know how your brain works. Here's a plan to do it in 45 days, with step-by-step exercises! Read more
The Science of Positivity
Stop negative thought patterns by changing your brain chemistry
Negativity is natural because our brains evolved to look for problems. This book explains how cynical thought habits get built in our brains, and how you can replace them with new habits. In just minutes a day for six weeks, you will build new neural pathways that find the good in your world as skillfully as you can now find the bad. Read more
I,
MammalHow to make peace with
the animal urge for social power
High-status animals get better mating opportunity & foraging spots. We have inherited a brain that rewards you with the good feeling of serotonin when you get respect. But the serotonin is soon metabolized so your brain is always looking for ways to get more. You can avoid "junk status" & enjoy more serotonin when you understand your inner mammal. Read more
Dopamine
Dopamine energizes you when you find a new way to meet a need. It's the brain's signal that a reward is at hand. The great feeling motivates the body to invest effort in pursuit. Dopamine is triggered by things that promote survival in the state of nature (food, mating opportunity), and anything associated with rewards you've experienced before. Neurons connect when dopamine surges, which wires you to expect a reward in similar settings. These connections trigger the good feeling with each step closer to a reward. This motivates us to do what it takes to meet our needs.
Serotonin
Serotonin rewards you with a good feeling when you gain a social advantage. Mammals compare themselves to others to avoid conflict. They make careful decisions about when to assert and when to defer. Serotonin is released when a mammal sees itself in the one-up position. Serotonin is not aggression but a nice calm sense that “I will get the reward.” The good feeling motivates a mammal to seek social advantage again. We can easily see this in our social rivals, though we tend to overlook it in ourselves and our allies. Each experience of social dominance connects neuron that tell you where to expect more.
Oxytocin
Oxytocin is the good feeling of social trust. A mammal can relax and lower its guard in the presence of trusted others. Touch and trust go together because those close enough to touch you are close enough to hurt you. The mammal brain makes careful decisions about when to release the good feeling of trust. If you step away from your trust bonds, oxytocin falls and you feel unsafe. We mammals are born into a surge of oxytocin, which creates attachment. Neurons connect, so the good feeling turns on when you see things related to past trust. Mammals build in-group trust through awareness of common threats.
Endorphin
Endorphin masks pain with euphoria. This allows an injured mammal to do what it takes to protect itself. Endorphin evolved for emergencies, not to flow all the time. The good feeling soon passes because pain is vital survival information. Pain tells you not to touch fire or run on a broken leg. Fortunately, small endorphin releases are stimulated by the exertions of laughing and exercise. “Runner’s high” only happens if you run to the point of pain. We are designed to laugh, not to inflict pain on ourselves.
But it's complicated
Habituation
The brain saves its happy chemicals for new rewards, and habituates quickly to old rewards. This is why we're often disappointed by the same-old thing, and why we're always seeking. Natural selection built a brain that rewards you for meeting survival needs, not for just sitting around. Survival is defined in a quirky way, alas: your mammal brain cares about the survival of your genes, and it relies on neural pathways built in youth.
Cortisol
Cortisol commands attention when a threat is perceived (internal or external). It creates the feeling that you will die if you don’t make it stop. Each cortisol spurt connects neurons that turn on the bad feeling when similar circumstances are met. Disappointment triggers cortisol. This promotes survival by alerting a mammal when expectations are not met, so it stops investing energy in an unrewarding pursuit.
Myelin
Some neural pathways become superhighways thanks to myelin. It coats neurons, so they're super-efficient conductors of electricity. Myelin is abundant in the brain before age eight, and during puberty, so the experiences of those years become your brain's infrastructure. When electricity flows effortlessly down your myelinated neurons, you feel like you know what's going on. Leaving your myelinated pathways can feel like a survival threat, despite your best intentions.
Mirror Neurons
When you see another mammal get a reward or risk pain, mirror neurons fire in the same pattern as if you were having the experience yourself. These special neurons mirror what you observe in others. Repetition build neural pathways, so without effort or intent, a young mammal wires itself to seek rewards and avoid pain in the ways it observes in those around it.
