This is the first book I recommend to anyone who wants to improve their writing. With Minto's Pyramid Principle as a follow-on.

My top 3: 1/ Edit ruthlessly. Every single word is reduced to its simplest form and pulls its weight--it has a damn good reason for being there. 2/ Aspire to write at a third-grade reading level. Readers prefer simple writing even when reading deeply technical content. 3/ Start your most important conclusions up front, not at the end. You're not writing The Sixth Sense. Do your reader a favor and tell them the big reveal first. You can then follow through and persuade the reader why your conclusions are right.

Bottom Line Up Front and "Anything worth reading is 10% of the first draft," are the two hardest procedural skills in writing.

It's just so much experience to avoid those mistakes.
