Some motivation to begin your week:
"I'm writing a book. I've got the page numbers done."
— Stephen Wright
Sometimes the hardest part is taking that first step. As Stephen Wright states, put down those page numbers. Take that small step, even if it is just getting one sentence on a piece of paper. If you need to, put the work aside and come back to it later in the day. Good writing is a process, and it shouldn't be rushed. The important thing to remember is to take that first step.
Have a wonderful week!
