Extracurricular activities?

Hello, I had a question about extracurriculars. I know they are very important to get into a "good" university, but how far do I need to go? My dream college is Cornell. I have multiple activities: Dance, volunteering every week, writing, and beekeeping. But when I was filling out my chancing profile, I see that for me to get into my dream college I better win a big award, be published by a well known publishing house, or be the founder of the organization and raise $100,000. What's realistic to accomplish? And what other activities can I pick up to have better chances? My interests include: Science and animals mostly.
