Over the last few years, these are the writing and personal development books that have helped me the most. Try any one of them on for size and you will be changed in a good way. Enjoy!
The 7 Habits of Highly Effective People by Stephen Covey (learned how to love properly, the best way to look ahead, and the difference between managing and leading)
Ask and It Is Given by Esther Hicks (my introduction into the Law of Attraction)
The Celestine Prophecy by James Redfield (entertainment plus personal development = a fun read)
