Should parents make decisions for their older teenage children?

In today`s fast paced society, parents and adult relatives play a significant role in shaping a child`s life. They teach them how to live, how to make a right decision, & struggle for achieving their goals. Most of the teenager thinks that they are able to make all decisions in their lives. In my opinion, I strongly agree that parents and adult relatives should make important decisions for their teenage children because teenagers are inexperienced, over-confident and do not realize the consequences that the important decisions can have on their lives.  

Teenagers being in the adult world and having their first experiences of their adult lives, think that they are capable to make their own decisions without parents opinion. However, most of the times, their friends influence their decisions. For instance, a student may get a scholarship into a top university, but just because of his/her friend is going to the college, he/she also follows to go to college too. This is not a creative or proud decision they have make. In this case the decision is obviously influential and in the future it may have great negative effects. So, parents or adult relatives should play their role to make decisions for their children.   

Secondly and equally important, teenagers mostly are over-confident to make up their own decision. The teenagers have not enter the practical life, they are still fresh and do not have any idea of how practical world works. Teenagers are living in a kind of fantasy world before entering university. They think everything is cool and perfect or too ideal such that their mind is too easy and simple to make decision. For example, teenagers might think that playing badminton in school definitely can get them selected on national team. This may be true in some cases, but usually it would not work out in this way. So if they neglect their study, just to concentrate on their sport, they are going to be definitely loss and might give a deep impact of their lives.   

All in as far as I concerned, I agree to stay that parents or adult relatives make important decisions for their teenage children because teenagers are lack of experiences and over-confident not be able to make decisions for themselves.
