Do you agree with this opinion that family is the most important influence on young adults?

I always think that family is the most important influence on young adults ，while others may take an different opinion, firmly believing that the key point which influence young adults most is the surroundings ,such as, teachers,classmates,and the person passed by .I never deny the faction of surroundings , but I will show you the reasons for my view . My arguments for this point are listed as follows.

observing objectively, you’ll always find that the little boy who eat little candy may have a doctor father,and the little gilr who dress appropriately may have a elegant mother. Besides ,singer's children may also singing well and athlete's children will also have a strong body. Why? That is, young adults who know little will imitate the person surrounding them when the child get used to the daily life. There is no doubt that the person is the families ,and this time is also the most important time for young adults.

A natural conclusion from the above discussion is that family is the most important influence on young adults.just like a Chinese saying goes "like father ,like son."
