we usually see some one does something only in one way even he have other choice to finish that thing. In my opinion, it is unwise to put all eggs in one basket.We know, once that way is not available we will have no other chance to turn back. In our daily life, we usually face many difficulties and problems. To solve these problems, we should make two or more plans to do it. If one idea is not available, we have the other plans. In a word, the chance is more for our success. For example, the airport and hospital make two plan for power providing because disaster will happen if they are out of power.
