I have a quote from Emerson on a magnet on the fridge. I bought it for myself a few years ago, and it has helped.
finish each day and be done with it.
you have done what you could.
some blunders and absurdities have crept in;
forget them as soon as you can.
tomorrow is a new day.
you shall begin it serenely and with too high a spirit
to be encumbered with your old nonsense.
Our Welfare State. Is it broken?
