There are many ways to help people.

Most doctors help people on a one on one basis most of the time, even if you are Singapore's top surgeon with multiple fellowships all over the world.
Except maybe public health doctors, researchers, healthcare admin (prolly at least a good 10-20 years later once you are more established) - this group helps a larger group / wider population at one go.
I used to think that I would enjoy the one-on-one interaction, but now looking back after 7-8 years into the profession, I might have picked something else.
