In 1982, Steven Callahan was crossing the Atlantic alone in his sailboat when it struck something and sank. He got into a life boat, but his supplies were    . His chances of surviving were small.      when three fishermen found him 76 days later, he was alive —much      than he was when he started, but alive.
His      of how he survived is fascinating. His cleverness —how he      to catch fish, how he evaporated (蒸发) sea water to       fresh water—is very interesting.
But the thing that        my eye was how he managed to keep himself going when all hope seemed lost, and there seemed no       in continuing the struggle. He was starved and      worn-out. Giving up would have seemed the only possible choice.
When people      these kinds of circumstances, they do something with their minds that gives them the courage to keep going. Many people in       desperate circumstances      in or go mad. Something the survivors do with their thoughts helps them find the courage to carry on      difficulties.
“I tell myself I can      it,” wrote Callahan in his book. “Compared to what others have been through, I’m fortunate. I tell myself these things over and over,      up courage…”
I wrote that down after I read it. It      me as something important. And I’ve told myself the same thing when my own goals seemed      off or when my problems seemed too terrible. And every time I’ve said it, I have always come back to my      .
The truth is, our circumstances are only bad      to something better. But others have been through the much worse, that is, in comparison with what others have been through, you’re fortunate. Tell this to yourself over and over again, and it will help you       through the rough situations with a little more courage.
