My favorite books are those that inspired me to take my level of activity up a notch. Here are four books that helped to take me to the next level in my life. Hopefully, they can do the same for you as well:

The Secret. If you have a clear picture of how exactly you would like to live your life but are not sure how to get there, Rhonda Byrne’s The Secret is for you. In The Secret, Rhonda shares a universal law, like the law of gravity, that she discovered when she was at the lowest point in her life. This law is the law of attraction.

The law of attraction states that your thoughts influence the events that happen in your life. If you focus your attention on achieving a goal, and believe that you can accomplish that goal, you will achieve it.

After reading this book, and discovering the concept of the law of attraction, my life has never the same. I began being more positive, and believed in myself, my goals and efforts much more.

In addition to explaining the concept of the law of attraction, The Secret shares techniques and strategies to use the law in our businesses, relationships and personal lives.

Toilet Paper Entrepreneur. You don't need large amounts of money to be successful in business. Starting a business with very little capital be a good thing. In The Toilet Paper Entrepreneur, Mike Michalowicz shares an analogy he coined when he was on the toilet and only had three sheets of toilet paper left to finish his business.

The premise of the analogy is that entrepreneurs who don’t start with large amounts of money actually have an advantage over those who do get funding from angel investors and venture capitalist. That's because financially constrained entrepreneurs will only spent money on the absolutely necessary expenses.

The book is absolutely hilarious. Many times I literally fell off my chair or bed laughing while reading it.
