Do not spoil what you have by desiring what you have not; remember that what you now have was once among the things you only hoped for
— Epicurus
We are, finally, all wanderers in search of knowledge. Most of us hold the dream of becoming something better than we are, something larger, richer, in some way more important to the world and ourselves. Too often, the way taken is the wrong way, with too much emphasis on what we want to have, rather than what we wish to become.
— Louis L’Amour
The highest activity a human being can attain is learning for understanding, because to understand is to be free
— Spinoza
