If you don't apply what you learn then all the knowledge in the world means nothing. The reason you learn is to put what you now know into practice. Do I even have to go any further, I should end this post right now and make it my shortest one ever. Hard work is great but when you apply the lessons you learn and pick up along the way, then suddenly your hard work becomes smart work. When you can figure out how to work smarter you will see results. When you can be more creative, add more value and create more depth because of the vast information you can pull from to apply to any situation in life and in business.
I challenge you to apply just ONE THING from every book you read moving forward.
