 Not to think about the past, the regrets, the mistakes, anything that may have happened. And not to worry about the future. So many people live for that day they all retire, for whether or not they have enough money in the bank account, or for whatever it may be. You may never see those days. I can't tell you how many people I know never saw those days. But to me, living in the present moment is so important. And it's also, to me, doctor, very liberating.
