What made a plumber? What made a wireman? What made a brickslayer? What made a glazier? What made a fabricator? What made a contractor? What made a draughtman? What made a designer?
What they know? What they do? How they know? How they do their work?
Actually there is no secret to know what they know. It's PLAYROLE. It's something people do by design.
All the jobs are done with the assistance of tools and technology, one way or another ; some involve more of it than the others.
It's technology and tool that make the job more than that person himself!
Have you ever found a keysmith working without that trade's machine and tool?
Have you ever found one designer presenting his work without the software?
In playing role one must understand the importance of tools and technology and the necessity of investing and keeping up with the related and relevant ones.
