Learn how to use a computer.

There was this great old teacher at my old school who wasn't too good with computers. Email? Got checked every couple of days. Attachments? Not a good idea. Internet? Well, he was ok with the basics, but unfortunately didn't know about things like saved Google searches and clearing the cache, which turned out to be a problem when he looked at some porn on his school computer. Hey, it was late at night, no kids were around, and he doesn't have a computer at home. But that was it, he was sacked. Bottom line: computer skills are more important than you think!
