Everyone has something to offer in this world.  Pay attention to everyone, because we learn from each other.  We attract many different people into our lives consciously or unconsciously.  By observing and/or listening carefully to others, you may be inspired by someone, or you may be reminded that not everyone is at the same level of awareness as you.  Either way, be grateful for whomever crosses your path, because there is always room for self-improvement.  My little grandson teaches me to be happy for no reason.
