I think education is important in a modern society, but it certainly doesn't guarantee success. On average, at least in the U.S. people's income rises with their education level. This has become more pronounced since the beginning of the industrial era and recently, the computer age. There are many exceptions, certainly. I can always find you people with talent but little education who were able to succeed. I can also find you well-educated people who have failed completely. On the whole, though, you have a better chance in a modern society if you are better educated. Also, if I was talking about a farming economy, education would not be as important, though this is changing too. It is a matter of playing the averages. I would consider a good education as a part of a path to success, but I certainly wouldn't count on it being the only key.

partly true

I think that an education is very imortant. It makes you go places in life

It's not always true. Because, many illiterate persons got a successful life, while many scholars or well-educated fellows committed suicides, after horrible losses. It's relative, but still true in many cases. Education helps a person to climb into higher social levels, and shortcut the way to success, especially in this Era. And it even became necessary - for a lot of careers-, but not sufficient.
