Write four lines of prose about: yesterday/today/tomorrow.
You can follow my example if you wish, or branch off and do something new and exciting.
That was a long harvest day. I am tired and have nothing of interest to say, so we'll just get on with things, shall we?
Yesterday I fell short of the man I wish to be. Today was somewhat better, but there were still far too many mistakes and pratfalls for my liking. Tomorrow... tomorrow I shall stand tall, rise above my shortcomings, stay true to my values, and be the man I've always meant to be.
And the cycle continues, forever unbroken.
