Hmmm...have a few items I think.
1.) Passing my Master's test to get my 4th degree in Tang Soo Do. I have one in Matsumura Seito Shorin Ryu as well, but it didn't mean as much to me as the one in TSD.
2.) This website. We've been doing this for over a decade. I've met so many people in the industry including Garriott, Molyneux, Itagaki, the entire Bioware team, the God of War team, etc. etc. etc. I could fill this page to capacity with just the people in this industry that I've gotten to meet. It's kinda awesome. Getting to meet a few of you was pretty awesome too!
3.) Served my country with honor and came out alive.
4.) Drifted a Porsche.
