50 is a great person. I was a little intimidated when I met him for the first time in 2006. I didn't know what to expect. It ended up we got along really well. That's why we decided to do a book together, The 50th Law of Power.

As most people when I entered the work world, suddenly people are playing games, being manipulative, being a little bit nasty, you get tricked or you're kind of naive and you do something and people come steal your idea.

It's okay to be kind of looking for what you want and trying out all kinds of different ideas and different course work, etc.

There's physical adversity, that if you are someone that likes exercise like I do, I exercise everyday. When you exercise, there's pain involved and so you're putting yourself through adversity in that situation.

So must be able to deal with the boredom that happens in life.

Ethics and power are separate. Ethics and morality. I think life would be miserable if there weren't some kind of code that people operated by, but history is full of many, many people who have gotten power by very unethical means, and people who were very ethical, who get no power, people who have the most brilliant, lovely, wonderful, nice intentions and bring about horrible things in the world because they don't know how to play the power game.

I have an argument that to master any field, it's simple: it's a function of time. How much you devote yourself to the process, how much experience you get, how much you're willing to expand your limits, how willing you are to develop your own style. If you're willing to put 10,000 hours, something amazing is going to happen.

When it comes to fertility, there are so may things that have to go right. In any one individual, there might be one major problem and two minor ones or no major ones and seven minor ones. Throw in another person's physiology, and it's complicated. I try to give people the knowledge that they can make as many changes as they want.
