At the end of a summer, as fall approaches, we can sometimes feel busier than any other time of year. We tend to work too much and exercise too little, assuming that unless we have an hour or more to spend at the gym on a regular basis, it’s pointless to even try to get in shape.

Well, here is my solution to that problem, and I think it’s a good one: Take just 30 minutes out of your busy day, and go on a gratitude walk. Make it special. Make it an event that you look forward to. View it as an opportunity for positive reflection. When you walk, make sure you move at a fast pace and reflect on things in your life that you are grateful for.

I am fortunate to live in both exciting New York City and sunny Southern California. (Being bicoastal is really a joy!) But this walk can be done anywhere—in the city or on the countryside. It can even be done on a treadmill.
