I wish I hadn't worked so hard; I wish I'd had the courage to live a life true to myself, not the life others expected of me; I wish I'd had the courage to express my feelings; I wish I had stayed in touch with my friends; and I wish I had let myself be happier.

I THINK IF YOU'RE GOING TO BE CONVENTIONALLY ROMANTIC YOU'VE GOT TO GO ALL THE WAY: A BEAUTIFUL DINNER SOMEWHERE LOVELY, WITH BOAT-LOADS OF FLOWERS, CHOCOLATES AND CHAMPAGNE.

Mind games? Maybe.
