That's why I keep the original raw or jpeg file separate. I make copies of the photos and use that file to work with. I also work saving several PSD and TIFF's at different times. So later if I think I went a little overboard with the enhancements I can step backwards. But that's also why I do a lot of my processing in Camera Raw first. So I can take the file to the point where I think I want it without it being destructive. After that if I usually use a filter it's because I want an additional special effect. But all my sharpening and cropping and real edits I've already done but it's done in such a way that I can step back and undo it easily. If worse comes to worst I even have the original folder to make more copies from. I don't just do it all then throw the working copies and the original out. That wouldn't be very smart. With CR I don't need to save as many PSD's as I used to because CR keeps all those edits in a side car but still I like to keep 3 or 4 versions of my photo at different stages so I can easily step backwards.
I don't really do that very often though go back and second guess myself. I have with some very old stuff, but that's mostly because I feel I can do more with the new version of PS/CR then I could then. I'm pretty aware of what I want to do and I usually know when I've done too much. I'm conservative on my sharpening and such to begin with. Unless I'm really going for a grunge effect or a retro one or I'm working with a photo that needs a lot of color, like one with an insect, I don't tend to over pop my photos. I almost always look at what I am doing and step back a tiny step from what I think I want, use just a tad less sharpening or whatever. It seems to work out best that way in the end.
