Difficulty

Life always presents us with a variety of difficulties. It has a far-reaching significance to us ,whether or not we can handle them reasonably.

How can we deal with difficulties in life? Different people have different views.Some people feel that if everything depends on their own ability, they are afraid that they are in trouble. On the other hand,they do not think they are capable enough to do it right. If their success and happiness depends on their parents and their friends, they will not feel anxious and depressed. In other words,they feel their destiny is better in the hands of others than their own. In contrast ,other people can always directly overcome difficulties and try to solve those difficulties with reason. Facing failure and [suspiciousness] ,they do not yield and do not hesitate, because they are convinced that the destiny up to themselves.
