From the very beginning of a person’s life one learns that the purpose of life is not uninterrupted pleasure. Every infant suffers pains and illnesses. We should not perceive illness and pain as negative. Suffering teaches us humility. We learn that we do not have complete power over ourselves.
The perfection of moral character consists in this, in passing every day as the last, and in being neither violently excited nor torpid nor playing the hypocrite.
Upon every hand we meet with those who have some secret resentment that is ever being nurtured within their hearts. They resent the success, or happiness of some one whom they think is less deserving than they are. They resent the just recognition that comes to others from work and long effort to excel. Or, they may resent being born poor - or resent the fact that they were even born!... Strive to excel, strive to achieve, where others have failed, and you will find no space within your mind to lodge resentment. Resentment is the child of selfishness, foolish envy, and inactivity... Our life upon this earth is too valuable for resentment of any kind. There is so much to do, so much to learn - so little time in which to live and work it all out.
Treat others as thou wouldst be treated; dispense not to others what thou likest not for thyself.
To live each day as though one's last, never flustered, never apathetic, never attitudinizing - here is the perfection of character.
I cannot teach you the ten principles of service. But a little child and a thief can show you what they are. From the child you can learn three things: He is merry for no particular reason; never for a moment is he idle; when he needs something, he demands it vigorously. The thief can instruct you in seven things: He does his service by night; if he does not finish what he has set out to do, in one night, he devotes the next night to it; he and those who work with him love one another; he risks his life for small gains; what he takes has so little value for him that he gives it up for a very small coin; he endures blows and hardship, and it matters nothing to him; he likes his trade and would not exchange it for any other.
