We usually see someone does something only in one way even he have other choices to finish that thing. In my opinion, it is unwise to put all eggs in one basket.We know, once the 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, it is easier for us to finish it. For example, the airport and hospital make two plan for power providing because disaster will happen if they are out of power.
