“The first, which we’ll look at in the next chapter, is a radical form of responsibility: taking responsibility for everything that occurs in your life, regardless of who’s at fault. The second is uncertainty: the acknowledgement of your own ignorance and the cultivation of constant doubt in your own beliefs. The next is failure: the willingness to discover your own flaws and mistakes so that they may be improved upon. The fourth is rejection: the ability to both say and hear no, thus clearly defining what you will and will not accept in your life. The final value is the contemplation of one’s own mortality; this one is crucial, because paying vigilant attention to one’s own death is perhaps the only thing capable of helping us keep all our other values in proper perspective.”
