The only rules and limits are those we set for ourselves

People really do think they have to choose between high stress and high reward jobs, and low stress and low reward jobs.

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 goal is not to simply eliminate the bad, which does nothing more than leave you with a vacuum, but to pursue and experience the best in the world.

I think willpower is very valuable.

I value self-discipline, but creating systems that make it next to impossible to misbehave is more reliable than self-control.

I discourage passive skepticism, which is the armchair variety where people sit back and criticize without ever subjecting their theories or themselves to real field testing.
