قصة الكتاب :
When the explorer comes home victorious, everyone goes out to cheer him. We are all proud of his achievement — proud on behalf of the nation and of humanity. We think it is a new feather in our cap, and one we have come by cheaply.\r\nHow many of those who join in the cheering were there when the expedition was fitting out, when it was short of bare necessities, when support and assistance were most urgently wanted? Was there then any race to be first? At such a time the leader has usually found himself almost alone; too often he has had to confess that his greatest difficulties were those he had to overcome at home before he could set sail. So it was with Columbus, and so it has been with many since his time.\r\n
