Here’s an experiment for you: Place a small bowl of M&Ms (or your fattening/sugary vice of choice) right within reach. Leave it there all day and then count how many you ate. Think that was a test of self-control? Now try putting a huge bowl in the same place. We’d venture to guess you’ll end the day with as few left at the bottom as when you started out with less.

Indeed, it’s hard to stop when it seems like you’re hardly making a dent. That’s because we tend to adjust our consumption based on what’s available to us – and we aren’t just talking about candy. Many people treat money the very same way.
