What Can I do to better my extracurricular in a year and a half time??

My extracurriculars right now

1. Published in a super prestigious journal(concord review)

2. Non profit - 200+ volunteers and more than the equivalent of 5,000 dollars raised(which is a lot since I am from a country whose currency is really weak). 3 years

3. NHS - President of Leadership, 2 years

4. Crosscountry - Varsity, 4 years

5. Science club - President 3 years, Member 4 years

6. Planning to attend either TASS/RISE

7. Community Service School club - President 2 years, Member 3 years

8. Caretaker of my younger sibling(Who suffers from a disease and gave me the idea to start the non profit). All four years

9. Planning to do research

What can I do to make my extracurriculars better or is there anything I should add?

I feel like I am all over the place.
