I recommend viewing your own importance from the per-spective of the next century-from a point when your good name will have dwindled to a zero, no matter how fabulous you might be today. A fundamental part of the good life is not being too full of yourself. In fact, there's an inverse correlation: the less you stand upon your ego, the better your life will be.

In the book

And write your assumptions down before a decision, so you can check later which ones were true. Gain altitude when you're stuck. When the trees close in, rise above them; step outside your own skin and watch the trouble as a spectator would; and view the wound from the distance of a century, where almost all of it shrinks.
