Here's me, back in 2002:
In this picture I am ten years younger than I am now, forty pounds lighter, and have very little discernible gray in my hair or beard. Anna and I had been married only a year, and we were still five years away from having our first child. I was only thirty-five, older than many newly-married men, true, but still young by many standards.
When I look back on pictures like this, I often think, "Wow, I wish I had realized then how wonderful my life really was. I should have appreciated it more at the time. I should not have taken it so much for granted."
And then I realize: My life today contains so many moments that someday I will look back on and realize were wonderful. Among the best things I can do for my wife, for my children, for myself, then, is to try and appreciate how wonderful my life is right now, while it's actually going on, to not take it for granted but to know it for the gift that it is.
I am blessed. But then, we all are.
