It's important to stay true to yourself. You have to know your weaknesses and recruit support when and where you need it.

If you fail to plan, you pretty much plan to fail.

You can look for external sources of motivation and that can catalyze a change, but it won't sustain one. It has to be from an internal desire.

Play with your kids. Limit their TV time. Get outdoors and chase them around. Wrestle with them. Walk the dog. Go bike riding. The reality is that your kids are not stupid, and they know when they are overweight Start walking the dog after dinner instead of watching TV. You don't want them going on the Web to find ways to lose weight. That's when you'll find them eating tissue paper because they read that a supermodel did it.

Your legs are not giving out. Your head is giving out. Keep going.

I want you to take a moment here and write down all the problems that are plaguing you at this moment, from big to small. Now ask yourself what you contributed in creating your current situation. Did the professor fail you because you never went to class? Did your boss yell at you because you were on YouTube instead of working?

So when it comes down to it, a calorie is a calorie is a calorie: There is only one moral of the story: burn as many damn calories as possible whenever you work out.
