"The happiness of your life depends upon the quality of your thoughts: therefore, guard accordingly, and take care that you entertain no notions unsuitable to virtue and reasonable nature."

"Very little is needed to make a happy life; it is all within yourself in your way of thinking."

"When you arise in the morning think of what a privilege it is to be alive, to think, to enjoy, to love ..."

"We must make haste then, not only because we are daily nearer to death, but also because the conception of things and the understanding of them cease first."

"Observe the movements of the stars as if you were running their courses with them, and let your mind constantly dwell on the changes of the elements into each other. Such imaginings wash away the filth of life on the ground."
