Do you back-up your work daily? I learned the hard way about doing that a long time ago. While computers are more reliable than they were years ago, it could still happen and be catastrophic if all your work were lost, especially those very productive days.
I find the easiest way to do this is with a thumb drive. You may even want to keep a few versions, in case you might want to go back and see a previous version you’d since edited out, then change your mind. But the biggest nightmare of all is losing your entire story to a hard drive crash. Computers and word processors have been the author’s best friend, but unless you had a house fire, in the old days with typewriters, you never lost your entire story to hitting the wrong command key.
