Finish every day

Finish every day and be done with it.
You have done what you could.
Some blunders and absurdities
no doubt have 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 yesterdays.

Emerson
