Undo My Changes?

You can use the regular ol’ Undo keyboard shortcut, Command-Z (PC: Ctrl-Z), but Lightroom lets you take the whole undo thing up a notch by keeping track of everything you’ve ever done to your image in Lightroom over in the History panel (in the Develop module’s left side Panels area). When you look in that panel, you’ll see each edit listed in order (with the most recent at the top). You can click on one to jump to how your image looked at that stage of your edit, and you can always return your image to how it looked when you first imported it by either scrolling to the bottom of the History panel and clicking on the entry called “Import” or by just clicking the Reset button at the bottom of the right side Panels area.
