Acting

Follow your passion - That is the line most people will say and that is right up to some extent. Follow your passion but only when you are confident of yourself. You love your passion as much as you love yourself. Acting and modelling in today's world is very demanding. I will suggest you to first take your passion as a side work but not as main work. I know it is too costly to pursue a course in R K Film Academy.
It would be better you talk with your parent and tell them everything what you want. It is your life and you have the right to think about your life. However, listen your parents also what their stand about it. Give them example of those people who did what you want to do. So talk to your parents and I know you can cope up with both. Do not leave your B.Sc at starting. Leave it when you realize that you will do something good in acting one day.
