I haven't bookmarked any quotes at the moment.
You have it easily in your power to increase the sum total of this world's happiness now. How? By giving a few words of sincere appreciation to someone who is lonely or discouraged. Perhaps you will forget tomorrow the kind words you say today, but the recipient may cherish them over a lifetime.
Only to the extent that someone is living out this self transcendence of human existence, is he truly human or does he become his true self. He becomes so, not by concerning himself with his self's actualization, but by forgetting himself and giving himself, overlooking himself and focusing outward.
People who say that life is not worthwhile are really saying that they themselves have no personal goals which are worthwhile. Get yourself a goal worth working for. Better still, get yourself a project. Always have something ahead of you to look forward to -- to work for and hope for.
But wait... my book has more:
Progress is impossible without change, and those who cannot change their minds cannot change anything.
Women wish to be loved not because they are pretty, or good, or well bred, or graceful, or intelligent, but because they are themselves.
Bad people are less a problem than indifferent people.
Look at things... as they can be.
