What is the reason for the bad fortune?

Bad luck only has some influence in this respect. The same person, the same job, the same bad luck, but his experience and attitude at work are different, and his life is different. All the above conditions are equal. A is an active and diligent person who likes to use his head when encountering problems, while B, on the contrary, is lazy and doesn't like learning, and everything is muddled. Then A can handle more things than B, and they are different, but in contrast, A has more advantages, because it is different to grow up in difficulties and improve their abilities. The combination of nature and nurture is a whole life, and all people will have difficulties, but they have different attitudes, actions, resources and directions.
