The only things I would change, would be the things that are impossible to change: the mine wouldn't have collapsed on my brother. But it did and it has shaped my entire life. It has not destroyed it, it did cut off some options, at the same time it helped me face the reality of life and death. That lead me to change some of my priorities away from achievement to focus more on relationships. On the other hand, if I could have my brother back, I could deal with being a more shallow person.
