Hmm, this question reminds me of a person I heard of a while back. He had always been sort of a timid person and had never really taken risks or put himself out there. But then he found out he only had 8 months to live. He all of a sudden took a completly different outlook on life and did things he had always been to afraid to do. He even got up the courage to ask out a girl he had always liked and she said yes! He told people he had never felt so excited to be alive than in those final eight months.
Now what I would do. I would spend as much time with friends, loved ones and family as I could. There are some people I would also want to make amends with, so I would do that too. I would also take a ski trip out to Colorado, Montana, and Utah!
