I think we spend too much time wondering why we're not good enough - we spend too much time over-analyzing, over thinking and overreacting.  We wast too much time putting ourselves down, so much that we never stop to see that, well, we are good enough.  You are good enough.  We spend too much time with out heads down and our hearts closed; and never get a chance to look up from the ground and see that the sun is shining and tomorrow is another day.
