Be not unwilling in what thou doest, neither selfish nor unadvised nor obstinate; let not over-refinement deck out thy thought; be not wordy nor a busybody.

If you separate from . . . everything you have done in the past, everything that disturbs you about the future . . . and apply yourself to living the life that you are living-that is to say, the present-you can live all the time that remains to you until your death in calm, benevolence, and serenity.

The whole universe is change and life itself is but what you deem it - either gratefully better than or bitterly worse than something else that you alone choose.

Men despise one another and flatter one another; and men wish to raise themselves above one another, and crouch before one another.

Take care that you entertain no notions unsuitable to virtue and reasonable nature.

Whatever may happen to you was prepared for you from all eternity; and the implication of causes was from eternity spinning the thread of your being.

Everything is mere opinion.
