  • For Scientific American Science Quickly, I'm Kendra Pirlois in for Rachel Feldman.

  • Hello and Happy New Year!

  • I love the first few days of a new year.

  • It evokes a feeling that change is possible,

  • that feeling in part leads some of us to set New Year's resolutions, an estimated 40% of U.S.

  • adults set resolutions any given year.

  • We promise ourselves that we'll save money,

  • exercise regularly, or spend more time with friends and family.

  • And yet, for many of us, as that feeling of newness fades, so too do our resolutions.

  • Some research suggests that as many as 88% of Americans give up on their resolutions within two weeks.

  • But it doesn't have to be that way according to Katie Milkman,

  • a behavioral economist at the Wharton School of the University of Pennsylvania.

  • She's the author of How to Change,

  • the science of getting from where you are to where you want to be.

  • Katie says there are science-supported tools that we can use to spark positive changes in our lives.

  • Doing so involves not only asking high-level questions about what we want to achieve and why,

  • but also finding ways to make the passwords achieving those goals while fun.

  • Here's our conversation.

  • In your book, you talk about how moments like a new year,

  • even a move, you talk about them as fresh starts.
