A few years ago two friends died in a very similar accident in the same area. Both Justin and the driver are extremely lucky to be alive. I know there will be some hard days ahead, but there is no doubt in my mind that Justin will continue to have a positive outlook on life.
The lesson I think we all can take from this is to simply be grateful for what you have instead of focusing what you're missing. If Justin can do it in his situation, we all can.
