We've all done it: Lost work. And as much as we'd like to blame the freak power cut at 1am, the "stupid application" for "crashing again" or the "heap of junk" that is our computer, the blame really rests with us: Quite possibly with our choice of software applications or hardware but, more than likely, with our work habits. Do you save religiously every five minutes? Do you use source control? Do you take off-site backups?
[I'm] sure that many of us would like to answer "yes" to all of the above questions but, unfortunately, many times it's the like-tos and wish-I-hads that are at the root of our problems with losing work.
