I'm sad to see that this fantastic book by Caroline Sharp hasn't been given more reviews. I came across it by chance when I was browsing for something entirely different, I thought it looked good so I bought it on a whim. I am so glad I did! It is filled with fantastic exercises to get you in the habit of writing regularly and about different things that you probably wouldn't normally consider. At the beginning of each exercise she gives a small anecdote which are usually humorous and interesting, she then outlines the task she wants to you attempt and finally explains the importance behind each task and the skills it will help you acquire/improve.
I have been trying to do one task a day, and I feel that the exercises she provides are already improving my writing, and my perspective and understanding of writing. Each task is also designed so that you can revisit them as many times as you like, so even after you have completed the exercises in the book it will still be a well of inspiration that is just as useful as when you turned the first page.
I would definitely recommend this book to anyone interested in writing; whether you are an aspiring author or an accomplished one with a lack of inspiration. This fantastic book is worth every penny!
