I like your style, you write like you think & it shows & it’s enjoyable. So thank you for writing here, for me (& others) to read.
I agree with Sergei Foldin, The War of Art is absolutely one of my favorite & most useful books! Two other books I recommend for every writer: Natalie Goldberg’s Writing Down the Bones & Anne Lamott’s Bird by Bird. Classics for damn good reasons. Another unwritten rule to improve your writing: when you finish writing, read it out loud. I promise you will catch tons of mistakes you won’t any other way!
Don’t worry about sounding like anyone else — read far & wide. And the more you write, the more your own voice will shine through.
Write on, you’re terrific!
