The philosophy of life would include things like how you decide what is “good” and “bad”, what “success” means, what your “purpose” in life is (including if you don't think there is a purpose), whether there is a God, how we should treat each other, etc.
A personal philosophy is your thoughts, beliefs, concepts, and attitudes about everything. It's your approach to leading your life. In the context of this article it's a series of phrases written by you which effectively summarize your values, goals, habits and the lengths you'll go to realize them.
The actual meaning of life is to fulfill your purpose in life and accomplish your goals. What I mean by this is, everyone has a purpose, of why they are living. None of us will be here if we all didn't have a purpose.
We live because of the happy things. We live because there are people who love us, and people we love back. We live because we want to find out things, and learn, and become able to do things that we would like to do. We live because others want us to, and we want them to live along with us.
There are at least two senses in which the term philosophy is used: a formal and an informal sense. In the formal sense, philosophy is an academic study of the fields of aesthetics, ethics, epistemology, logic, metaphysics, as well as social and political philosophy. One's "philosophy of life" is philosophy in the informal sense, as a personal philosophy, whose focus is resolving the existential questions about the human condition..
The term also refers to a specific conception of philosophizing as a way of life,endorsed by the German Lebensphilosophie movement whose main representative is Wilhelm Dilthey[3 and several other Continental philosophers such as Henri Bergson and Pierre Hadot.
