The Part of Your Brain That Makes You Hard to Quit

There's a structure sitting in the middle of your brain that most people have never heard of. It's called the anterior midcingulate cortex, and researchers who study willpower and elite performance think it might be the most important piece of neurological real estate for becoming the kind of person who doesn't fold under pressure.

Here's what it does. Every time you do something hard. Not something you enjoy. Something genuinely difficult, uncomfortable, something your brain resists. That structure activates and, over time, grows. Literally. Physical volume increases in people who regularly do things they don't want to do.

The inverse is also true. In people with depression, chronic passivity, and what researchers describe as learned helplessness, that structure shows measurably less activity and less mass.
