Need an idea...

<p>So I need to write this essay for a scholarship where I am suppose to talk about my career goals and how they will affect society. My problem is that since I am still in high school, I don't know what I'm going to major in...maybe bioengineering. Even then, I don't want to say something like "I want to cure AIDS" yet I don't have anything specific to say...</p>

<p>Any ideas on how I can get started? (About 300 word essay)</p>
