“The mind that is anxious about future events is miserable.”

“True happiness is to understand our duties toward God and man; to enjoy the present, without anxious dependence on the future; not to amuse ourselves with either hopes or fears, but to rest satisfied with what we have, which is abundantly sufficient.”

“True happiness is to enjoy the present, without anxious dependence upon the future, not to amuse ourselves with either hopes or fears but to rest satisfied with what we have, which is sufficient, for he that is so wants nothing. The greatest blessings of mankind are within us and within our reach. A wise man is content with his lot, whatever it may be, without wishing for what he has not.”

“Were all the geniuses of history to focus on this single theme, they could never fully express their bafflement at the darkness of the human mind. No person would give up even an inch of their estate, and the slightest dispute with a neighbor can mean hell to pay; yet we easily let others encroach on our lives—worse, we often pave the way for those who will take it over. No person hands out their money to passersby, but to how many do each of us hand out our lives! We’re tight-fisted with property and money, yet think too little of wasting time, the one thing about which we should all be the toughest misers.”

“And what’s so bad about your being deprived of that?... All things seem unbearable to people who have become spoilt, who have become soft through a life of luxury, ailing more in the mind than they ever are in the body.”

“It is the power of the mind to be unconquerable.”

“Putting things off is the biggest waste of life: it snatches away each day as it comes, and denies us the present by promising the future. The greatest obstacle to living is expectancy, which hangs upon tomorrow, and loses today. You are arranging what lies in Fortune's control, and abandoning what lies in yours. What are you looking at? To what goal are you straining? The whole future lies in uncertainty: live immediately.”
