You may think that..
... you are completely insignificant in this world. But, someone drinks coffee from the favorite cup that you gave them, someone heard a song on the radio that reminded them of you. Someone read the book that you recommended, and plunged headfirst into it. Someone smiled after a hard day's work, because they remembered the joke that you told them today. Someone loves them self a little bit more, because you gave them a compliment. Never think that you have no influence whatsoever. Your trace, which you leave behind with every good deed, cannot be erased.
