Rewrite the famous quote as if a ten-year-old wrote it.

“Finish each 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. You shall begin it serenely and with too high a spirit to be encumbered with your old nonsense.”
― Ralph Waldo Emerson
Sure thing. The requested rewrite is as follows:

"Complete each day and be over with it. You have completed what you could. Some mistakes and oopsies will be on your mind; quickly don't worry about them. Tomorrow it starts over. You should start it calmly and not hold on to the bad thoughts from before."
