It isn't work that makes you tired, it's your mental attitude.

criticism is dangerous, because it wounds a person's precious pride, hurt his sense of importace and arouse resentment.

One of the most tragic things I know about human nature is that all of us tend to put off living.

So if you aspire to be a good conversationali st, be an attentive listener. To be interesting, be interested. Ask questions that other persons will enjoy answering. Encourage them to talk about themselves and their accomplishments

If we are so contemptibly selfish that we can’t radiate a little happiness and pass on a bit of honest appreciation without trying to screw something out of the other person in return—if our souls are no bigger than sour crab apples, we shall meet with the failure we so richly deserve.

Life is bigger than processes and overflows and dwarfs them.

Ask questions instead of giving direct orders.
