And man alive! _If we never learn to laugh we will never learn to live._ We must not forget that there can be more than one use made of energy.
In the same way that electricity might be misused so might energy be placed in the wrong service.

We must not waste any time, therefore, in getting this energy of ours worked into _enthusiasm_ ...

enthusiasm for our life work, for our fellow man, _for the zest of life_.

We must throw ourselves into the battle and carry the standard.

We must leap to the front, not waiting for the other fellow to show the way.
