On Being Lucky

I've been thinking a lot lately of what it means to be lucky.  About three weeks ago I was in a basically terrible accident with little to no injuries. There was high speeds, going on to the barrier, and rolling and rolling. It was scary, and I have developed somewhat of a fear of slow-moving trucks and lane changes. I also experience neck pain, and quite a bit of it. On the other hand, I have no broken bones, no internal injuries, and no being dead. So that's good.
I consider myself quite lucky. Part one of luck is most certainly a blessing, I am blessed.  Part two of luck is understanding, understanding that luck isn't the lack of bad things happening, but instead the ability to be happy anyway. Part three of luck is action, this means that luck involves active choice making—I choose to see this as something that happened, and something to move past— this choice is not easy, and I struggle with it, but I'm trying.
Unrelated to luck, I have this struggle with impossibilities and limitations. I don't like that they exist, and I tend to ignore them. Sometimes this is good and helps me accomplish great things. And sometimes it is bad and helps me be so tired that I can hardly breathe.  But I figure, if I am to be alive, I may as well be living.
