+# Resetting A Reset
+
+Sometimes we run commands like `git reset --hard HEAD~` when we shouldn't
+have. We wish we could undo what we've done, but the commit we've *reset* is
+gone forever. Or is it?
+
+When bad things happen, `git-reflog` can often lend a hand. Using
+`git-reflog`, we can find our way back to were we've been; to better times.
+
+```bash
+$ git reflog
+00f77eb HEAD@{0}: reset: moving to HEAD~
+9b2fb39 HEAD@{1}: commit: Add this set of important changes
+...
+```
+
+We can see that `HEAD@{1}` references a time and place before we destroyed
+our last commit. Let's fix things by resetting to that.
+
+```bash
+$ get reset HEAD@{1}
+```
+
+Our lost commit is found.
+
+We cannot undo all the bad in the world. Any changes to tracked files will
+be irreparably lost.
