Hmm
I wouldn't let it change me. I'd still go to work, carry on with my old routine, and attempt to keep myself grounded.
OR
I'd go absolutely nuts, buying Portsmouth FC and becoming chairman. I'd travel everywhere in a Chinook, sprayed blue with a pompey logo on one side and "we hate scummers" on the other.
I'd smoke massive cigars, drink the finest shant and go out of my way to be "gauche" moneyed.
