They say that a wise man can express wisdom of a lifetime in one sentence. Each one of the quotes below make me feel that way. I will keep adding to this list as I unearth more gems.
1)"Hope is not the conviction that something will turn out well but the certainty that something makes sense, regardless of how it turns out." -- Vaclav Havel
2)"There are two ways to live your life. One is as though nothing is a miracle. The other is as though everything is a miracle." -- Albert Einstein
3)"The difference between a smart person and a wise person is that a smart person knows what to say and a wise person knows whether or not to say it." -- Quote found on the wall of a recreation center office in Berkeley, California
4)"Success is getting what you want. Happiness is wanting what you get." -- Dave Gardner
5)"We do not see things as they are; we see things as we are." -- Talmud
6)"Security is mostly a superstition. It does not exist in nature, nor do the children of men as a whole experience it. Avoiding danger is no safer in the long run than outright exposure. Life is either a daring adventure or nothing. " -- Helen Keller
7)"This is the true joy in life: the being used for a purpose recognized by yourself as a mighty one; the being a force of nature instead of a feverish, selfish little clod of ailments and grievances complaining that the world will not devote itself to making you happy. I am of the opinion that my life belongs to the whole community, and as long as I live, it is my privilege to do for it whatever I can. I want to be thoroughly used up when I die, for the harder I work the more I live. I rejoice in life for its own sake. Life is no 'brief candle' to me. It is a sort of splendid torch which I have got hold of for the moment, and I want to make it burn as brightly as possible before handing it on to future generations." -- George Bernard Shaw
8)pain is inevitable but suffering is optional.- unknown
9)"The happiness of those who want to be popular depends on others; the happiness of those who seek pleasure fluctuates with moods outside their control; but the happiness of the wise grows out of their own free acts."
- Marcus Aurelius
