In old cowboy #books I read as a kid there were people who had lots of #skills--saddling horses, caring for livestock, fixing fences, maintaining tools, cooking on the trail, harnessing oxen, repairing wagons and barrels, etc. They were always in demand and someone always needed what they were doing.
I think people who understand file systems, network protocols, a couple of coding languages, graphics, etc. are kind of like that, now.
EDIT: As @Shanmonster has reminded me, the physical cowboy skills don't stop being awesome just because lots of our world shifted to an information/service model. If you can code AND fix a fence... damn. You're killing it.
