Some people bounce back in response to setbacks; others break. We often think that these responses are hardwired, but fortunately this is not the case. Philosopher William B. Irvine combines key lessons from the ancient Stoics- thinkers including Marcus Aurelius and Seneca-with modern psychological techniques such as anchoring and framing to develop a surprisingly simple strategy for dealing with life’s unpleasant surprises. These include minor setbacks like being caught in a traffic jam or having a flight cancelled, as well as major setbacks, like those experienced by physicist Stephen Hawking, who slowly lost the ability to move, and surfer Bethany Hamilton, who lost an arm to a shark.
