Of the list, I liked 22 - go back and cut 10% of your word count - pretty good one that helps keep the story, essay, or whatever clear and concise. Some of them were completely obvious - write, and then write some more, and read grammar books. Some were just dumb, like 25 - Read lots of books. Both good and bad. Why would I want to read a bad book? Some books are better than others - no shit. You could stick to good, better, and best books while learning what differentiates bad from good....
Writing doesn't make you a better writer. Reading makes you a better writer. But certainly not reading this trash.
It's just a list of things. Related to writing I guess, but still. Could probably be done in ten bullet points. A list of 70 just drops down to literary diarrhea at some point.
'Talk to people' indeed.
