I'm afraid I won't be good enough

I really, really want to be a petroleum or chemical engineer. I love math and science, and I'm in the process of building a light bulb. I'm just scared that since I am a girl I won't be taken seriously, and I am scared that I won't be good enough. What should I do? Drop my dream or do it?
