Initial Reflections

This post will shamelessly replicate the cliché format I am familiar with present in philosophy- asking questions.
Is there a concrete classification of philosophy? (Classification referring to the following questions, different than a definition). What are the uses and implications of philosophy in our personal and social lives? Does the relevancy exist only on specific occasions or on a daily basis? Can anyone weigh the importance culturally, socially, intellectually? Does it rely on an importance that differs with varying perceptions? Can it be classified as subjective- impossible to understand unless one "experiences" the truth of claims made?
Validity must be considered as the philosophical questions and evaluations have existed for centuries. Personally a complete understanding has not presented itself to me. I have more examining to do of the specific concepts of philosophy and how they incorporate into the aspects of my life. I do, however, anticipate my overall scope to be transformed, my knowledge enhanced, and there to be an acquired respect and appreciation of great philosophers.
