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

In my opinion teenagers need the help of their parents because when you are a teen, your mind and your ideas can change because you don´t know at 100% what you want but when you reach your mature age or legal age this is when you can choose by yourself and your parents can not choose for you. Their opinion can guide you but only that nothing more.

In adition, the person who is going to work and study is you, you are the only who need to learn about the life walking alone, meeting people, and at last trying to find the happiness.

also, there are a lot differnt studies and you are young to try most of them and don't worry if you fail, this is something that you need to grow and be stronger, people are made with scars.
