Do you write with passion or do you just write anything?
Own each piece of work you write by making it authentic. For instance, don't claim to be an expert on a topic you know nothing about just to get paid. It's one thing to write a well-researched piece or a piece with personal experience. But it's a whole other ball game to wrote something you have absolutely zero knowledge or experience in.
You may be able to slide past the radar with that at times. But it will eventually catch up to you and ruin your entire writing career. Instead, write what you know through studies or experience. Your clients will appreciate your authenticity. Readers can see right through writing that lacks connection from the writer. On the other side of the coin, they also value and feel content that contains the writer's authentic knowledge and experiences.
Be authentic. Be you. Be hired. Be read.
