Lou Holtz once said, 

"Ability is what you're capable of doing. Motivation determines what you do. Attitude determines how well you do it."

When I was in high school, I saw the following quote every day before and after practice, before and after games.

 "Whether you think you can or you think you can't, you're right." 

At the time, I didn't really believe it. After all, just because you think you can do something doesn't mean you can. And there were times when I thought I couldn't do things, but ended up surprising myself by being able to do them.

But as I got older, I realized how true this quote is. Your mind is a very powerful tool. It can control much of how you perform. So if you go into a situation full of anxiety and worry that will affect how well you do.

However, if you go into a situation knowing that you will accomplish what you want to accomplish, chances are you'll do just that. Why? Because you've just set a goal and often times when you set a goal, you find yourself working toward it, preparing yourself to reach it.

If you don't have that positive mindset, however, and you never set that goal, do you think you're going work toward it? 

Remember what Zig Ziglar said,

"You can't hit a target you cannot see, and you cannot see a target you do not have."
