Ninety-nine percent of people believe they can't do great things, so they aim for mediocrity.

Perfection is an impossible destination

The way that you become world-class is... by asking good questions.

The truth is that since the first book, I have wanted to emulate Benjamin Franklin and put together a healthy, wealthy and wise trilogy and so healthy was 'The 4-Hour Body,' wealthy was 'The 4-Hour Workweek' and then wise is 'The 4-Hour Chef.'

The brain is where most people really screw up.

There is an infinite selection of things that I could test in life, so I generally will look for a critical mass of word that comes back to me. At this point I have hundreds of friends who are the best at what they do, arguably number one in the country or in the world. I will oftentimes just kind of throw a volley out to people, ask them what they're obsessing on or what they find interesting that's on the fringe. If the same answer comes back a few times, I'm like, "Okay."

For all of the most important things, the timing always sucks. Waiting for a good time to quit your job? The stars will never align and the traffic lights of life will never all be green at the same time. The universe doesn't conspire against you, but it doesn't go out of its way to line up the pins either. Conditions are never perfect. "Someday" is a disease that will take your dreams to the grave with you. Pro and con lists are just as bad. If it's important to you and you want to do it "eventually," just do it and correct course along the way.
