Most complex tasks are solved using abstractions. To create an abstraction one groups lower-level concepts, what I will call primitives in this text, and make them interact in a pre-defined way. Abstractions are present at all levels in a system. Computers work based on electric signals.

We had more than one hundred people on those sessions, and feedback was often pretty good. After my last run I told my business partner that this was my last time running those workshops.
