I took a Dale Carnegie course in New Zealand in 1974 when I was 24 years old. It brought me out of my shell back then and helped me in my job as manager of a ski shop in Auckland. I think I was a bit young and naive to fully appreciate how important that training was for me. So, 46 years later, I decided to read the book again. It is amazing stuff! I can't recommend this book AND course enough! It has again helped me, in my retirement volunteer work.
