Saving for retirement typically takes decades.
And Charles Duhigg, author of the book "The Power of Habit," says that to create new savings habits you need to reward yourself more.
Many people struggle with the idea of working toward a savings goal that can be years or decades off, according to Duhigg.
"If you are trying to save money, it is essential that you come up with some weekly routine where you reward yourself," Duhigg said. And the reward doesn't mean you have to spend more money.
