In a previous post, I mentioned I believe the usual advice given to writers (or, rather, to people who want to write) may not be that good, if not downright useless. And if one wants to be controversial, you might as well start with a big bang:
“Read a lot. Reading will make you a better writer,” or variations of the same. It seems logical, common-sensical. But if you think about it, it’s a bit like saying that if you want to be a good musician, you should listen to a lot of music, or look at many paintings if you want to be a painter. A kind of craftsmanship by osmosis.
