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
21 ．His chances of surviving were small．
22 when three fishermen found him 76 days later, he was alive —much
23 than he was when he started, but alive．
His
24 of how he survived is fascinating．His cleverness —how he
25 to catch fish, how he evaporated（蒸发） sea water to
26 fresh water—is very interesting．
But the thing that
27 my eye was how he managed to keep himself going when all hope seemed lost, and there seemed no
28 in continuing the struggle．He was starved and
29 worn-out．Giving up would have seemed the only possible choice．
When people
30 these kinds of circumstances, they do something with their minds that gives them the courage to keep going．Many people in
31 desperate circumstances
32 in or go mad．Something the survivors do with their thoughts helps them find the courage to carry on
33 difficulties．
"I tell myself I can
34 it," wrote Callahan in his book．-Compared to what others have been through, I'm fortunate．I tell myself these things over and over,
35 up courage．．．"
I wrote that down after 1 read it．It
36 me as something important．And I've told myself the same thing when my own goals seemed
37 off or when my problems seemed too terrible．And every time I've said it, I have always come back to my
38 ．The truth is, our circumstances are only bad
39 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
40 through the rough situations with a little more courage．
