I can help you write better. Please get in touch if you would like some writing coaching.
And here's my book on the subject
Perfect Written English
I don't like the publisher's title for this book, as I think perfection is a pointless aim, unless you're Shakespeare. But we can all improve. This book will show you how.
My basic premise is that every word should carry the reader forward in some way. I look at ways that writers fail to do this and start boring the reader instead- and show how to avoid these traps and, instead, make your writing energetic and engaging.
I look at the process of creating a piece - how to overcome the tyranny of the blank piece of paper, get stuff down, then progress to editing and refining.
Basics such as parsing (kids don't learn this any longer), punctuation and grammatical mistakes are covered, too.
