Going through the sample chapters and within 30 seconds finding myself chuckling at the beginner mistakes the book is pointing out
not to make, for example presenting labels and values where values on their own would be sufficient [1]. And further down on the same page 'Combining labels and values' (I would almost always make the mistake of not combining them) - seeing the wrong and right ways side by side makes it obvious, even to me.
EDIT purchased the pdf, will try to skim today.
