Is there a good job for people with shaky hands?

Hi. My hands tend to shake a bit. I am not nervous, but people think I am when I am holding something. I don't consume caffeine at all. I'm not sure why my hands shake. I am trying to learn piano, but my hands are a bit shaky lol.

Anyways, is there anything that would suit me? I don't think I can be waiter because I'll be shaking with the plate. I am also afraid of being a cashier because I'll be shaking with the change too and make the customer uncomfortable. I am trying to find my first job and im 21
