These are 3 of my favorite words "Knowledge is power". I always read about what I would like to be. It is because how much I read about my future job (as an example, it may be about your health etc.) will keep me a strong person about my business. How much read about my business will make me a " Specialist " on my business which will bring my client's confidence , faith to me. " Be fit " with your clients. There are many personalities. Absolutely, you can not learn everything by reading books to understand people's behaviors, we need times , we need to experience for it. After all, I believe I am going to be a good consultant for my clients.
