I think that part of the success of "Radical Honesty" is not directly about honesty, but about taking risks. So many people live a bland life because they cannot fathom "making waves". This is normal. However, "Radical Honesty" forces us to break these laws. I think life is meant for excitement, and this is one way of achieving it. (As Tim Ferriss and others have pointed out) Happiness and Sadness are two sides of the same coin. Its boredom that makes life miserable.
Yeah. When you've realized the phrase "shit settles on the bottom of the pool" sticks in your mind, alongside the phrase "my co-workers are settling" then you're on the path to misery.
