My main one is my battle with cancer which hopefully is over. Can't say it for another 3 years.

Some of the things I had to go through is blocked from my memory. I don't want to remember it. I learned what real pain was, and all the things I use to worry about suddenly weren't important.

It taught me to love life, persevere, not rush things, and take it one step at a time. Most of all, to kick some ass, and fight.
