We must keep up our activities.

We have taken the earth and are turning it into something to serve us--therefore the need of fine bodily preparedness.

Nothing can take the place of achievement and it comes through physical and mental efficiency.

The one must not be neglected for the other; both must be cultivated and developed alike in order that each may help the other.
Happiness comes only to those who take care of themselves.

It is the natural product of _clean-mindedness_.
