"You have to be positive every single day. You have to put effort into it daily, because no one else is going to do it for you."

Get out of your own static comfort zone by moving forward with momentum and power that positive thinking can give you. Every time a negative thought comes at you, zap it. Replace it with a positive thought. That takes energy, but the result will be stamina - positive stamina, a necessary ingredient for success.

Sometimes you just have to be tough. I use the example of a brick wall. Is there a brick wall in your way? Fine, that happens. But you have a choice. You can walk away from the wall. You can go over the wall. You can go under the wall. You can go around the wall. You can also obliterate the wall. In other words, don't let anything get in your way. Get a balance, and then let the positive outdistance the negative. Be positively persistent.

Optimism can be learned, and it can make a huge difference in life. No matter how large and intimidating a challenge might be, facing it with optimism is the thing you can do to manage, shape and eventually triumph over it.

The bottom line: Trash the pessimistic attitude.
