I remember one morning back in 2002. Sitting in my cube, enjoying one of the perks of my new office job–free soda–I found myself disgusted that over the course of the morning I had consumed six Mountain Dews.

Six Dews a day was not unusual for me at that time. That’s an additional 1,020 calories per day in liquid. In 2010, that’d be almost 3 million additional calories in my diet had I continued that pace.

Fortunately, I stopped drinking soda shortly after that moment of disgust when I found six empty cans of Mountain Dew in my wastebasket.

What small changes can you be making right now that eight years down the road will make a big difference?
