I found this quote yesterday and it articulates perfectly what I have come to believe. If you want to be effective and happy, be of service. In everything you do, seek to be of service and you will never want for business or friends.
“I don’t know what your destiny will be, but one thing I know: the only ones among you who will really be happy are those who will have sought and found how to serve.” Albert Schweitzer
