There's a reason why Robert Greene's books are sure-fire bestsellers. They are not only interesting and inspiring - they can be life-changing. His first book, "48 Laws of Power," written in 1998, dealt with 3,000 years of the history of power, turning them into forty-eight well explicated laws, according to Amazon.

Here are some of the best bits from "48 Laws of Power."

1. Guard your reputation with your life

Japanese samauri would take their lives in a ritual called "Seppuku" to regain their honor after an embarrassment. It makes sense. No one can read the real you, so you are as good as what people think of you. Your reputation affects the way people treat you, and the opportunities that come your way.

"Reputation is the cornerstone of power. Through reputation alone you can intimidate and win. Once it slips however, you are vulnerable, and be attacked on both sides," states the book.

Everyone commits mistakes and there are ways to get back on track, but as much as possible, put your best foot forward. And no, we don't necessarily completely agree with Greene. There's no need to open your enemy's holes for the public's opinion to hang them. You do these things in political arenas, not in your nine-to-five job where peace is preferable.

2. Win through actions, never through arguments

Sometimes we have to argue on our way to making things happen. We have to battle a thousand questions to get our project proposals approved. But it never stops there. Once approved, you have to make things happen. Commit to your deadlines and milestones. Be grateful for every opportunity. Keep your word.

3. Pay the perfect courtier

Be pleasing. Yield to superiors and command your subordinates in the most graceful manner. Without compromising principles, be nice. Complement hard work and fine sense of fashion. Pack great Christmas presents. Develop sincere and wholesome friendships. Find things to love in everyone.
