Effort is not a means to lead us to happiness. Effort itself is happiness.

Success always demands a greater effort.

To keep a lamp burning, we have to keep putting oil in it.

The structure of world peace cannot be the work of one man, or one party, or one nation...it must be a peace which rests on the cooperative effort of the whole world.

We know the reward is peace on earth, goodwill toward men, but we cannot win it without determination and concerted effort.

The natural thing to do is to work-to recognize that prosperity and happiness can be obtained only through honest effort. Human ills flow largely from attempting to escape from this natural course. I have no suggestion which goes beyond accepting in its fullest this principle of nature.
