Extracurricular ideas?

I am currently a freshman in high school. My extracurriculars include NJHS (next year I expect to get accepted into National Honor Society as well) and a decent amount of community service hours (typically I do about 30 per year).

I'm passionate about writing, art, and coding, but also a beginner in all of those fields. I would like to get into a few programs outside of school to show colleges how I can turn my passion into something productive and beneficial. Are there any opportunities that I can seek out?

All help is appreciated!
