Should teenagers decide about their own future or guided by their parents?

Nowadays, teenagers have to make a lot of decision about their future. We have to decide about what do we want to study, what do we want to choose, etc. 

In many cases, we are influenced by our parents, family, friends, and we don´t stop to think which are our opinion. 

Is good that our parents or friends give us their opinion because they know us. In addition, we are in a period of time where we are confused and indecisive and they can help us. 

But also we have to learn to make important decisions because in the future, we will not have anybody that make it for us. 

In conclusion, teenagers should allow our family give their opinion but we have to have the last answer.
