Which element between nature and nurture plays the major role in childrens personality and development is always a controversial problem. Of course, which you prefer depends on your own experience, life style and emotional concern. Here, I would like to illustrate my point of view about it.
Admittedly, different nature determines people have distinguished starting points in their lifetime. To beginning, in light of medical research, a persons blood type has considerable influence to his character. General speaking, for example, a person whose blood type is A means that his personality is amiable and tender probably. Besides, the physical condition, even appearance may influence a persons development. Statistics shows that beautiful people are more confident than others, because they do not need to worry about the prejudice from public. Obviously, some parts of our personality have been decided when we born.
On the other hand, although nature is important during the course of shaping personality, we cannot ignore another essential element, nurture. There are many factors which affect the development of children, both parental support and education being vital influence. It is reported that the kid whose parents are divorced is more likely has psychological troubles than those with a harmonious family. By contrast, as we all know, good education will positively cultivate a persons personality and improve his self-restraint in a big way.
In summary, from what has been discussed above, we may safely arrive at the conclusion that partly because of different nature, partly because of different nurture, people have their unique personality.
