I have noticed over the years that my greatest returns have come from selfless investment in other people. Sometimes when you find someone you can help and you extend yourself to do so, never really expecting a direct return on that service, the investing can go on and on. Yet, I have found, when you least expect it, those investments in people bear great fruit. At times, people who I have served in this way have come back to help me in dramatic, tangible ways.
One must be careful not to let this observation taint the way they think about the people they are helping. Still, there is much for which to be grateful.
