A mistake I made early on in my freelance business was not using Grammarly to back up my work. All along, I knew that my writing often lacked clarity, and to a lesser degree, tone. As soon as I began using Grammarly Premium, everything improved. Whether you write as a hobby or you get paid, don’t do what I did. Sign up with Grammarly, and thank me later. There is a free version, but Grammarly Premium has a lot more to offer, for less than $12/month.
