Never put off till tomorrow, what you can do the day after tomorrow.
Mark Twain (Author and Humorist, alias Samuel Clemens)
Modern saying:
I used to crastinate. I got so good at it I decided to go pro.
One can always go backwards in time.
Today, I'm doing nothing because I started doing it yesterday and I wasn't finished.
Don't give up on dreams. Go back to bed.
