Many strides have been made in the study of the human brain, and some of them can tell us why we spend more time worrying than we do being happy. Prehistoric structures in our brains still keep us on the alert for danger, and in this modern, information-saturated world, these structures are the source of worry, nervousness, and even depression – the feelings that fight against our need for safety, comfort and connection with others.
The good news is that all it takes to increase your level of happiness is learning how to expand positive feelings when you have them. You can make any good feeling last for more than a moment if you practice “holding on” to it.
Groups of neurons in the brain fire together during pleasant experiences, and if those experiences happen repeatedly, they begin to wire themselves together, creating a “neuronal association” custom tailored for happiness.
