Fitness is not something to be attained. It is inside you the whole time– it need only to be revealed. It's as if someone has hidden millions of dollars in your home and all you have to do it get up every morning and look for it. This is why I enjoy it. Everyday I do it, I find that money. Good health is not obtained, it is revealed.
