Young writers should be encouraged to write, and discouraged from thinking they are writers.

It is the abiding concern of thinking people to preserve what keeps men human-to save our contact with nature of which we are a part.

We are the only species which, when it chooses to do so, will go to great effort to save what it might destroy.

That is all the National Parks are about. Use, but do no harm.

It should not be denied... that being footloose has always exhilarated us. It is associated in our minds with escape from history and oppression and law and irksome obligations, with absolute freedom, and the road has always led West.

It is the beginning of wisdom when you recognize that the best you can do is choose which rules you want to live by, and it's persistent and aggravated imbecility to pretend you can live without any.

Any life will provide the material for writing, if it is attended to.
