“The thirst of desire is never filled, nor fully satisfied”

All difficult things have their origin in that which is easy, and great things in that which is small.
Lao-Tzu

“Life is not a continuum of pleasant choices, but of inevitable problems that call for strength, determination, and hard work”

“At bottom every man knows well enough that he is a unique being, only once on this earth; and by no extraordinary chance will such a marvelously picturesque piece of diversity in unity as he is, ever be put together a second time.”

Most things break, including hearts. The lessons of life amount not to wisdom, but to scar tissue and callus. - Wallace Stegner
