Mark, I constantly worry that, if learned what I really need to know about the equipment I use to make my living, I wouldn't have any time left to work.
We have multiple PC and Mack systems for data management and graphics, keyboards (of course), cameras, editing suites, recording devices, video equipment and lost more.
I have to be satisfied to learn only what I need to know to get my part of a project and leave the rest to my son or others to really dig in a learn operation.
That makes me feel a little stupid and vulnerable.
