Good Reminder

I read the following in an Assembly Language book, of all places. Thought it was a good reminder:

I say this only because so many of you are considerably younger than I, and may forget in the fever of young life: Time passes, and so do the people who believe in us, and urge us through the walls as we hit them so that we may arrive at midlife with something to show for it. Fathers and mothers, grandparents, aunts and uncles can add immeasurably to our lives, and often do, even when we're too busy to notice. Cherish them while you have them, because cherishing them after they're gone is a lonely business indeed.
