I first read this book years ago when I began speaking at a Toastmasters group. At first, it helped me with my impromptu speaking. Later, it helped me to begin making small improvements in my daily actions (the slight edge technique). I was very disappointed it was out of print at the time and I couldn't buy a copy for my own library. Recently, a fellow Toastmaster member found it...and bought a copy for me. I was so grateful -- this is a book to read again and again.I recommend it to all my clients...Deceptively valuable.
