It can be easy to forget to save, especially when you get really into it and get idea after idea and lose track of how much time has passed. Plus sometimes I'm guilty of "gambling" my chances by deliberately not saving too often when the file size gets too big and the saving process becomes painfully slow don't want to spend more time saving than working
Luckily it's a problem I got on my last computer more than this one, Maybe I save more now - or maybe technology doesn't suck as much as it used to
Gawd, tell me about it; the place where I live is prone to frequent and unexpected power outages, so it wasn't uncommon to be in the middle of something on my computer when BAM...screen goes black and there went all my work!!! Dear gawd, it'd drive me to tears sometimes...T-T...but I learned my lesson and now I save EVERYTHING, important or not, several times while I'm working just in case.
