What should I do to make my extracurriculars stronger?

Policy debate
Varsity/JV softball
Editor-in-chief of my school newspaper
Blog (opinion pieces + book reviews)
Service project for teaching English to immigrants
Writing club
Asian culture club
Senior Thesis - it’s sort of an extracurricular and sort of an elective, basically a yearlong research project

For writing club, it’s actually for a state writing competition but regionals is the day of the March SAT so I can’t go
For debate, I’m going to try my hardest to get a leadership position but it’s super competitive
Asian culture club - I could get a leadership position if I wanted but the club is dying
