A wise man once told me that life is a roller-coaster, sometimes you're up and sometimes you're down. If you like something or you want to do something, do it! fight for it! because the person who never risks to do something would never now what he's able to, or what he could have done. So no matter what people say about you or tell you to do, you should keep doing what you like (if it's a good thing of course), have faith, and hopes.. and you'll achieve every goal that you have.
