No book can be so good, as to be profitable when negligently read.

Luck never made a man wise.

A good person dyes events with his own color . . . and turns whatever happens to his own benefit.

Let the man, who would be grateful, think of repaying a kindness, even while receiving it.

Men can be divided into 2 groups: one that goes ahead and achieves something, and one that comes after and criticizes.

A good conscience fears no witness, but a guilty conscience is solicitous even in solitude. If we do nothing but what is honest, let all the world know it. But if otherwise, what does it signify to have nobody else know it, so long as I know it myself? Miserable is he who slights that witness.

There exists no more difficult art than living.
