I'm going to outplay you. That's the mentality I have, and you should want to outplay me.
I was always a kid trying to make a buck. I borrowed a dollar from my dad, went to the penny candy store, bought a dollar's worth of candy, set up my booth, and sold candy for five cents apiece. Ate half my inventory, made $2.50, gave my dad back his dollar.
I don't consider myself a goody-goody, but I like to be perceived as classy.
