Does Having Good Grammar REALLY Matter?
My thoughts? Yes and no.
When it comes to writing for fun on these free to read sites like Wattpad, having good/flawless grammar really doesn't matter. Not unless you're out here trying to get noticed and land a publishing deal - then, of course, it helps to have perfect grammar. If you write primarily for fun, don't stress out about commas and apostrophes. Don't put that kind of pressure on yourself, haha.
