I started writing everything instead of thinking about sentence structure first. Once I have written a lot, I go over it and apply the learned rules, shorten, remove redundancies, etc. I also used the paper format, and instead of writing from scratch I now build up piece by piece, which is much easier and organised.
I'm being more conscious of my writing as I can be prone to use more words than needed. I have also found myself looking more closely at others' writing when I am approving their work.
