Hello,

Learning is continuous and there isn't any particular age to pursue your passion. As long you believe that you can achieve your goal you don't have to focus on what others say or think about you. Yes, you will face obstacles while you are on the pursuit of your passion but that shouldn't let you stop and make you think about them. First have a discussion with your parents and them about your goals, the course of actions that you have planned to reach your goals and tell them how passionate you are. They will surely support you if you are confident enough to pursue the course you wanted. They might not understand it initially, but do not loose hope, put your efforts constantly to make them understand.
