Mental toughness is a popular buzzword not just among athletes, coaches, and sport psychologists, but in the popular media as well.
Did you know that if you eliminate one can of soda per day from your diet and change nothing else, you will have lost about 15 lbs. by this time next year?
Or that if every household in the US replaced one 60-watt light bulb with a CFL bulb, the energy saved would power all the homes in Delaware and Rhode Island?
That’s nice, but what’s your point?
My point is that tiny changes, over time (or multiplied by large numbers) can lead to some pretty big results.
