Rock on . . .

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 and with too high a spirit to be cumbered with your old nonsense.
This day is all that is good and fair.
It is too dear with its hopes and invitations, to waste a moment on the yesterdays.

Ralph Waldo Emerson
