（Daniel Gilbert）出版過一本著名的書《快樂為什麼不幸福？》（Stumbling on Happiness， - Annie Duke

Identifying a negative outcome doesn't have the same personal sting if you turn it into a positive by finding things to learn from it. You don't have to be on the defensive side of every negative outcome because you can recognize, in addition to things you can improve, things you did well and things outside your control. You realize that not knowing is okay.

SIX STEPS TO BETTER DECISION-MAKING Step 1 — Identify the reasonable set of possible outcomes. Step 2 — Identify your preference using the payoff for each outcome — to what degree do you like or dislike each outcome, given your values? Step 3 — Estimate the likelihood of each outcome unfolding. Step 4 — Assess the relative likelihood of outcomes you like and dislike for the option under consideration. Step 5 — Repeat Steps 1–4 for other options under consideration. Step 6 — Compare the options to one another.

Barry Schwartz points out in his book, The Paradox of Choice, that this kind of sheep-in-wolf's-clothing decision is more likely to come up the more options you have to choose from. The greater the number of available options, the greater the likelihood that more than one of those options will look pretty good to you. The more options that look pretty good to you, the more time you spend in analysis paralysis. That's the paradox: more choice, more anxiety. Remember, if the only choices are between Paris and a trout cannery, no one has a problem. But what if the choices are Paris or Rome or Amsterdam or Santorini or Machu Picchu? You get the picture. THE ONLY-OPTION TEST For any options you're considering, ask yourself, "If this were the only option I had, would I be happy with it?" A useful tool you can use to break the gridlock is the Only-Option Test. If this were the only thing I could order on the menu . . . If this were the only show I could watch on Netflix tonight . . . If this were the only place I could go for vacation . . . If this were the only college I got accepted to . . . If this were the only house I could buy . . . If this were the only job I got offered . . . The Only-Option Test clears away the debris cluttering your decision. If you'd be happy if Paris were your only option, and you'd be happy if Rome were your only option, that reveals that if you just flip a coin, you'll be happy whichever way the coin lands.
