It was more than a year ago, but I'm still kicking myself over losing a USB Flash drive that contained the most current stories and writing projects I had on file.
I forgot a cardinal rule of working with computer files: BACK IT UP. Some of the stuff had earlier versions of stories on file on a hard drive between my desktop computer and my laptop, but I had foolishly kept the major stuff - especially a gathering of short stories I was planning to put into a new anthology - onto that one USB stick... and then I couldn't find it.
If I'm lucky, it just fell behind some furniture that's too heavy to lift up at the moment. I'm not desperate enough to re-arrange the entire townhouse to find it. However, it's frustrating me enough to curse my very existence.
If I had to, I could recover some of the works and edit them back up to where I'm sure I had my finished drafts, but I am definitely missing several key stories I would love to include in that planned anthology to make it all tie together in a nice theme.
REMEMBER MY SINS, WRITERS. BACK UP EVERYTHING YOU GOT.
