If you have had a bad day

Finish every day and be done with it
You have done what you could, some blunders
And absurdities no doubt crept in ?
Forget them as soon as you can.

Tomorrow is a new day, begin it well And serenely with too high a spirit to be encumbered with your nonsense
This day is all that is good and fair, it is too dear with it's hopes and invitations to waste a moment on the yesterday's

Ralph Waldo Emerson
