written by Jeff Olson. This book came highly recommended by my good friend Kemal Mavi from Turkey. He said it was the number one personal development book and I should take time to read it. I took his advice and purchased the book in 2012. Amazon delivered it one morning and before I returned from work, my 16 year old daughter had started to read it and was slowly and systematically bending the pages and punishing the spine and binding! She enjoyed the book so much she kept it in her room and I did not have the courage to get a tetanus shot and employ the US Navy Seals to retrieve it! When the 8th anniversary edition came out in 2013 I pre-ordered the copy with strict instructions that no-one could read it before I did! It was worth the wait, the Slight Edge philosophy is to make small daily steps that compound over time will make you successful in your career, relationships and financial goals. If you are only going to buy one personal development book this year then this is the one. An excellent choice for your summer reading.
