    We overestimate both the joy of wins and the pain of losses.

  2. IDEA 2 OF 6

    When we picture the future, the brain fills missing details without telling us.

    The imagined event feels complete but is mostly invented.

  3. IDEA 3 OF 6

    Presentism

    We project today's feelings onto the future.

    Shopping hungry is the classic example.

    The psychological immune system

    People recover from setbacks faster than they expect because the mind finds ways to make sense of them.

  5. IDEA 5 OF 6

    Ask someone who's there

    The best predictor of how you'll feel is how people currently in that situation feel, more than your own imagination.

  6. IDEA 6 OF 6
