Extracurriculars?

Hi there!
I’m a community college student that is majoring in Finance and I was wondering if my plan for extracurriculars are good enough.

  • Part time job- Cashier (currently)

Future plans for extracurriculars:

  • Volunteer as a translator at a hospital(even though its something I want to do, my mom doesn’t think that I’ll be able to handle it since my second language is not very fluent; I could hold up a conversation)
    -Join Model UN at my college.
    -Create an IM app for my college since the messaging system here is terrible. I do have some programming skills so I don’t think I have much of an issue here…

What do you think? Should I add more extracurriculars? Especially for the first one, how can I convince my mom to allow me to volunteer? What other leadership positions I should look at?
