Awesome story my man. I'm sorry for the losses you experienced that day, I'm glad it shaped you to be a better person. A lot of people don't view tragic accidents the same way as you. Some people spiral into a life of negativity as retaliation to the incident. It's good to hear that you've honored your friends passing by gaining a new viewpoint on life for the better. There aren't a lot of people who are positive let alone can inspire an atmosphere that other people to remain positive with. From the few times I've interacted I can tell your on a path to spread good vibes and connect good people.
I just recently lost a friend so I can understand some aspects of your pain.
Good vibes to you and everyone else!!
