I don't know about changing things, because there were a couple things done that made me the person I am today.

-listening to a stock broker talk us out of our investment, costing my parents their retirement and me a nice sum for my bank account
-take the generator to a better mechanic (a week before it burned the house down)
-not fill the generator when hot and ran out of gas after only 30 minutes (something clicked in my mind, just didn't act on it)
-RIGHT DECISION - fought with doctors about getting skin grafts
