Everyone has a philosophy, even if they don't explicitly define it. Many people think philosophy is esoteric, with no practical use in life, yet they make decisions all the time based on their own philosophy. It is also impossible to understand history without an understanding of the philosophical ideas that drive the actions of individuals and nations. I think it's important to know what you think, and why you think it. I think it's important to discover your unchecked premises and make certain they are valid. I think it's important to make sure you don't hold on to contradictions. And, I think philosophy is very important to living.
"...Joy, exaltation, beauty, greatness, heroism, all the supreme, uplifting values of man's existence on earth, are the meaning of life--not the pain or ugliness he may encounter...one must live for the sake of such exalted moments as one may be able to achieve or experience...happiness matters...the essence of life is the achievement of joy, not the escape from pain."
"Life is not about finding yourself; life is about creating yourself."
