+### I want to discard specific unstaged changes
+
+When you want to get rid of some, but not all changes in your working copy.
+
+First strategy, stash all good changes, reset working copy, reapply good changes.
+
+```sh
+$ git stash -p
+# Select all of the snippets you want to save
+$ git reset --hard
+$ git stash pop
+```
+
+Alternate strategy, stash undesired changes, drop stash.
+
+```sh
+$ git stash -p
+# Select all of the snippets you don't want to save
+git stash drop
+```
