Learn more to earn more. Books are abundant, they are full of the information that you are looking for. While reading a book is great, it is important that you find an accountability partner to help you implement those things that you read.
As a Coach/Mentor I hear over and over again how much my clients actually implement when they are being held accountable. A book cannot help you if you do not actually use it.
Happy Reading and Networking
