Hey William! Great question.
I try and write every day too. 100 words, 500, 1,000… and sometimes I’ve even got 3,000. Often it’s 4–5 times a week. It’s 100% true that the only way you get better at writing is by writing. I used to have this nasty habit of editing in the middle of my stories and blogs. A friend of mine taught me that’s not the way to write because, half the time, when you edit the things you wrote don’t even make it into the final draft. I realized he was right. In the words of Brene Brown, “everyone has a SFD (shitty first draft).” While writing every day is a great habit to pick up, a bad one is not revising and editing. You need time away from your piece to see the flaws and errors. You also need time to hone your style and voice throughout the piece and coax the magic out of it. I would also encourage you to do what you recommended: Research your piece. I’m really glad to have gotten in a habit of doing that because you’ll find sometimes you’re wrong, and had you proceeded it could have been embarrassing. Other times that it gives you insight into what other people are saying and thus new things to say in your piece.
Another thing I do is have my friends that will shred my work take a look. I don’t understand why people who write turn to their friends to review their work when it sucks simply to get a pat on the back. As Donald Miller once said:
If you’re turning it [your writing] in to your friends to get affirmation, that’s fine. But what plumber shows off their work to their friends? It’s just a craft. What you need is critical feedback from another plumber. It’s not about you, it’s about having a working toilet so to say.
Anyway, that’s my advice! Hope it helps!
