Wow Matt, Happy Birthday!
I had this idea that you were in your thirties!! Isn't that funny that I made that assumption about you. I just had my birthday recently and it always reminds me of what I've done and what I still want to do. I seem to take stock at that time of the year. When I hit a milestone I seem to think about the past, etc. even more.
I'm not 50 yet and won't be for a little awhile but I hope by then I will still strive to make photographs I care about. It seems the older I get the less I worry about other people's opinions and just concentrate on doing!
