I've talked before about a major worry I have, which is related to the early part of this thread.
I use graphics software and equipment (Mac based) Research and word processing software (PC based, and, believe me, they don't talk very well to each other, yet), Camera, video editing, audio recording interfaces, arrangers and lots of other software and computers. If I personally learned how to do everything I need to do on every piece of equipment, I'd never get any work done.
I just extended my agreement with an Italian staircase manufacturer to introduce custom staircases and design a builder/remodeler program for the United States. This will take about 5 years, so I'll be pushing 80 when it's all over.
My son is my IT guy, recording engineer, video editor, research analysis, roadie and bass player for my trio.
I'd be up a creek without him.
