+The kernel of wisdom is moderation in all things
+-----------------------------------------------------------------------------
+
+* It's easy to become despondent, but don't. While security is never
+  perfect, even a little effort will improve things a lot. You might
+  run faster than others, so the bear won't attack you.
+
+* It's easy to try too hard, but don't become a cryptography or
+  security absolutist. While it's good if everyone tries their best,
+  and improves their cryptographic defences over time, don't despair
+  if what they or you have isn't perfect.
+
+* **Cryptography absolutism** is when you say it's not worth using
+  cryptography at all, unless you're protected against every
+  conceivable scenario.
