The way to get better at writing is to write.I would say that's part of the way to get better at writing. But I'd add, to paraphrase Stephen King from On Writing[1],
"To get better at writing, write a lot and read a lot."
Granted, King was speaking mainly to writers of fiction, but I think the advice holds just as well for technical writing or anything else.
