8 keystone habits that can transform your life

Having strong willpower

Duhigg says “dozens of studies show that willpower is the single most important keystone habit for individual success.”

It all comes down to self-discipline. How do you know if you have it? One way to measure self-discipline, Duhigg writes, is to put people in a room with cookies and radishes and assign them one of the foods. Those who eat the other food, which will likely be the cookie, aren’t using their willpower.

He cites a 2005 University of Pennsylvania study that says students with high self-discipline perform better than those with a high IQ. “They had fewer absences and spent less time watching television and more hours on homework,” Duhigg writes.
