A sentence ends with a period and a period denotes an ending.
If you keep rereading the same sentence over and over, you'll never get to the next sentence.
Writers stuck editing the same sentence over and over never write a new sentence.
People on rewind, running the past over and over never move on.
When this happens, they wrestle with those things in the past that went "wrong." The frustrating part for them is that you can't "right" those "wrongs."
So while every second, every minute, every hour and every day ends with a period, editing and rewriting isn't an option.
You have no choice but to write the next sentence.
And the next.
