Who am I, and what do I need?

Laying in bed last night it struck me. A concept so simple I couldn't believe that it had taken me this long to stumble upon it. Yes it's a question, but more so it's a way of life. Too many times people lose there way by getting caught up in things and ideas that simply don't apply. Are you being defined by the material things you surround yourself with, or making a legacy based on personal and spiritual achievement? I realize I'm getting a bit philosophic, but these concepts ground themselves in everyday situations. What does this mean to you? Well it could be a turning point in your life, or simply a bunch of nonsense. Who am I, and what do I need?
