Best productivity/performance based jobs/careers?

[sgh]

was wondering if there are particular performance based jobs where you're paid/evaluated based on your skills/productivity while working? (I know
commission is one type; eg: sales/selling) So what might be other most
interesting sales jobs/careers you know?

what about physical tasking type jobs?, like delivering. (either indoors or outdoors)



with regards to bike courier companies within downtown. anyone know any
bike couriers that'd like to share their experience? what are daily duties like? what 's a typical day in the life like?

are there some differences between the various courier companies? do bike couriers get a bad rep in general? (or just some that ride more reckless than others?)

Realtor is a good one. If you can get enough clients and do enough work you will make huge dough.

As for bike couriers, I find they do get a bad rep from drivers and from people in general. I wouldn't think of bike couriers matching your topic at all, but maybe I'm wrong. The ones I've dealt with were usually happy go lucky hippies that don't seem too concerned with productivity/performance based pay.
