The future is purchased by the present.
All theory is against freedom of the will all experience for it.
Life cannot subsist in society but by reciprocal concessions.
Man alone is born crying, lives complaining, and dies disappointed.
To be happy at home is the ultimate result of all ambition, the end to which every enterprise and labor tends, and of which every desire prompts the prosecution.
Exercise is labor without weariness.
Let me smile with the wise, and feed with the rich.
To keep your secret is wisdom but to expect others to keep it is folly.
Money and time are the heaviest burdens of life, and... the unhappiest of all mortals are those who have more of either than they know how to use.
