People telling you what you can or cannot do or what you should or shouldn't do are basically robbing you of learning from your own mistakes which is very important. We have to make mistakes in our early years to learn from them and grow. Your mistakes and failures will contribute to the person you'll become later in your life.

Don't be afraid to make mistakes, those are part of our journey.

(Btw, this includes institutions such as banks who think they can tell you what you can or cannot do. They're not your legal guardian.)
