Success depends in a very large measure upon individual initiative and exertion, and cannot be achieved except by a dint of hard work.
Firmness in enduring and exertion is a character I always wish to possess. I have always despised the whining yelp of complaint and cowardly resolve.
Truth and mercy require the exertion - never the suppression, of man's noble rights and powers.

I have found that no exertion of the legs can bring two minds much nearer to one another.
