Although shopping makes Lisa happy, Jean says that walking 10,000 steps a day is a much healthier way to boost your mood. So far, the walking is paying off. "It's kind of challenging to try to get to that 10,000 steps a day, so it's like a little competition within myself," says Lisa.
The more Lisa walks, says Jean, the more it will feel like a natural part of her life. "It's not so much that she's breaking the shopping habit," Jean says. "She's replacing it with a good habit. And research has shown you have to do anything 21 times in order to make it a habit."
