Remember happiness doesn't depend upon who you are or what you have; it depends solely on what you think.

We can't win friends with a scowling face and an upbraiding voice.

I deal with the obvious. I present, reiterate, and glorify the obvious - because the obvious is what people need to be told.

...the best possible way to prepare for tomorrow is to concentrate with all your intelligence, all your enthusiasm, on doing today's work superbly today. That is the only possible way you can prepare for the future.

Remember that the people you are talking to are a hundred times more interested in themselves and their wants and problems than they are in you and your problems.

Anyone can do his work, however hard, for one day. Anyone can live sweetly, patiently, lovingly, purely, till the sun goes down. And this is all that life really means.

Self-expression is the dominant necessity of human nature.
