I think I learned how quickly life can change, and how one needs to be prepared to flex with these changes. People can very easily be killed by so-called "stupid" injuries, and I was lucky enough make it out of this relatively intact. I've lost many friends in my line of work, and try to consider myself lucky for being able to live my life the way I want to. I think the key to getting through these injuries is to focus on what you still have. Life is just a constant test of our ability to handle loss, and focusing on this loss can make you misanthropic. Things could be a lot worse, so why not enjoy what we can?
