This short book has been a help to me. It’s well-formulated and sensible. Zinsser argues that the best way to learn something, anything, is to write about it.
It’s impossible to write seriously on a subject without thinking deeply about it. Zinsser delves into several examples of good writing from authors: how they assemble their arguments and information, describe the subject(s) in question, and bring the readers into a narrative through their writing.
These are skills I’m working to develop.
