Problems, problems! Some would-be problem solvers are so overwhelmed by the problem that they usually fail. There are others who approach the problem calmly and practically, and usually solve it. Still others - only the truly inventive - find a unique solution to the problem in order to prove a point. For example, Alexander the Great, an ancient Greek ruler, was said to have been challenged to untie the Gordian knot. In mythology, this knot was fastened to a wagon and was thought to be impossible to undo. The great ruler was able to accomplish the task easily, however. He simply cut the knot with his sword! Tradition has it that Christopher Columbus was once given a challenge, too. In 1493, he attended a banquet in his honor, where he was questioned about how he had coped with the difficulties of his voyage to the New World. Columbus replied by challenging his questioners to balance an egg. When they couldn't, he did. How? He cracked the shell to create a flat bottom!
