Every one has an absolutely different life to others.But the books just told us the same story from famous people or heroes.When we grow up, we obviously found that the only way which could lead us to success is to use the correct methods to solve our own problems.The methods usually come from people's experiences or mistakes.Sometimes, the elders have experienced the same things what we will do, in that case, they don't want us to make the sane mistakes that they have made.We should listen to the elders and learn from them.But for the young people, this is hard to do,they always laugh at the elders and think there are much former viewpoints in their mind,they are not fit for the modern world.Until they made a lot of mistakes and missed some great opportunities, they suddenly understand that the elders were correct.It is also a sign of maturity for every one.I emphasize the importance what we can learn from theelders doesn't mean that learning from books is unimportant.We need more and more knowledge to change the world to be a better one.but the knowledge should be connected with specific reality,the most important thing we should remember is that we are going to solve problems ,not going to use knowledge to prove we are better than others.
