Everyday I spend at-least 20 minutes to read a positive and educational book to enhance and expand my thinking. Reading helps me in gaining the knowledge and expertise by studying and learning from experiences of many a successful people.
Reading helps me learn from myself for I hear my voice from the books written by others. This particularly helps me for I know my shortcomings (though not all) and books fuel that internal fire to get better by the day (and night).
I would strongly recommend readers of this post to also read "FUEL the energy you need to succeed" by Wes Beavis.
