Read your writing aloud
This one simple thing will boost your writing up to the next level.
Better yet, if you can (and you can do it on any phone now), record yourself reading your writing, then watch it. If you don’t think you have time to do this, FIND TIME. It's important.
Why?
Because as you read aloud, you’ll hear things you can’t see. They’ll jar your ear. Those are the things you need to fix.
And when you watch yourself read, you’ll almost see it as a movie, an actor (you) acting it out on the screen, and in the places you cringe you’ll know you have to go back and fix your store, and you’ll know how.
You’ll remember it vividly from watching yourself.
