When you have a strong body but a weak mind you are a meat-head.
When you have a strong mind but a weak body you are an egg-head.
When you have neither you are useless.
When you have both you are a force to be reckoned with.
In order for man to succeed in life, God provided him with two means, education and physical activity. Not separately, one for the soul and the other for the body, but for the two together. With these means, man can attain perfection. —Plato
The damned thing is if you weren't born smart you will never be smart.
On the other hand, if you were born weak (or, more likely, allowed yourself to become weak) you can make yourself strong through vigorous exercise.
I have good news, friends. Dumb people don't read, it is therefore highly likely that you are a smart person.
The question, friend, is will you put your smarts to good use and develop your body along with your mind?
Will you become whole?
Or are you satisfied being half of what you should be.
Do you care to attain perfection? Do you aspire? Do you strive? Do you give your best?
