Following is from the website of Brian Tracy. It is a section from one of his books and is definitly worth sharing.
Some things in life are optional, and some things in life are mandatory. Taking your next vacation to the Caribbean is optional. Building a personal library and becoming an excellent reader is mandatory. It is no longer something you can choose to do or not do. It is absolutely essential and indispensable for your success.
A great many people do not read very much. Fifty-eight percent of adult Americans never read a nonfiction book from cover to cover after they finish school. The average American reads less than one book per year. In fact, according to a Gallup study of the most successful men and women in America, reading one nonfiction book per month will put you into the top 1 percent of living Americans.
It takes regular, persistent reading and studying for you to improve, to move to the front of your field. It is not optional.
