A few years ago, I self-published a booklet of writing tips for kids. It was available only on Amazon for kindle. I always meant to revise and make it available more widely but until now I haven't had the time to do so but now it is available on the major sites and drastically revised. It's also available in print.
Note: Rather than issuing a new edition, I replaced the previous file on Amazon. Current owners of the book should be able to simply request the update. At least I hope so!
I should perhaps mention that it not only contains information about creative writing, writing reports and essays, etc. but also has a section on public speaking--because there are some simple tips that can make speaking easier and more compelling.
Perhaps you're wondering why it says (And Adults). As much as we want to, sometimes we don't have time to wade through long books about writing or public speaking and the material is as applicable for adults as it is for kids.
If you're interested, I hope you'll check it out. Here's the information:
