I can't say this enough: Imitate the writers you admire. Would-be basketball heroes copy the moves of the players they admire.
For example, when I was 15 years old I first read William Saroyan's The Human Comedy. I didn't know much about writing, but I knew I wanted to write and that I wanted to write with his warmth. Saroyan's writing gave me permission to express my heart on paper. That's one kind of imitation.
The other is to copy their words. When you read something that makes you pause and say, "I wish I had written that," copy the words. File them. Read them occasionally. As you copy and ponder the prose, you're absorbing their style.
Don't just copy best-selling writers. I can think of several top-grossing writers. It's not their mastery of the craft that makes them sell, but it's their plots or the material they cover.
I started with two writers I like, and neither of them was in my field. That didn't matter and may have been a positive factor. I couldn't steal or copy their prose, but I could learn syntax and phrasing that equaled theirs.
I find superior writers;
I imitate them so that I can become better than they are.
