Manual Prático de Redação Empresarial

I read it when I had nothing to do. I got it from a school book club (????). And it did no harm.

It's a book about writing in a business context, with guidance on clarity, formality and how to structure documents. Maybe it added something to my way of thinking. But not much. A lot of the content felt designed for far more formal corporate communication than the kind I actually deal with.
