A lot of the work in, say, construction or restaurants involves visual and motor flexibility. It also requires adaptability, in terms of answering questions, giving people directions, or taking orders.

So there's no typical day, but I transition through the course of my business day by doing everything from construction meetings on the development project under construction to design meetings for an upcoming apparel delivery to acquisition meetings about projects we're looking to acquire.

I started at an agency called Intertalent. You copy scripts, you pick up people's dry cleaning, you take their dogs to the vet, you deliver packages, you do whatever they want you to do.
I've done everything from research to stuffing envelopes.
In some environments, roles shift and change each period depending on what the company's needs are. On the other hand, many functional roles can become very repetitive if you perform similar tasks over and over again.
