Well written. Well said.
A word of caution, I’d take the liberty of adding, here. In the process of “wanting to” affect a “respectable” number of people and their lives, you also would be letting them affect your life; and as that number may increase, it might change you from time to time, depending on the kind of people you interact with.
So, all you have to be careful about, is to be attached to each of them and yet stay detached.. because the loss of a loved one in today’s world has a much higher probability (Referring to Japan-tragedy and Middle-East crisis).
There is a hairline difference between affecting and being unknowingly-affected.
