I came across a couple of quotes today that beautifully express my current life philosophy:

"Do not believe in anything simply because you have heard it. Do not believe in anything simply because it is spoken and rumoured by many. Do not believe in anything simply because it is found written in your religious books. Do not believe in anything merely on the authority of your teachers and elders. Do not believe in traditions because they have been handed down for many generations. But after observation and analysis, when you find that anything agrees with reason and is conducive to the good and benefit of one and all, then accept it and live up to it."
The Buddha

"This life is yours. Take the power to choose what you want to do and do it well. Take the power to love what you want in life and love it honestly. Take the power to walk in the forest and be a part of nature. Take the power to control your own life. No one else can do it for you. Take the power to make your life happy."
Susan Polis Shutz

And this one just for fun:

"I used to think it was awful that life was so unfair. Then I thought, wouldn't it be much worse if life were fair and all the terrible things that happen to us come because we actually deserve them? So, now I take great comfort in the general hostility and unfairness of the universe."
Marcus, Babylon 5
