Thinkable from my Mom

What do you call these things of which abound in a mother's life - the sayings and bromides, such as the Serenity Prayer, that are set on thick paper and mounted on the wall or wherever. "Deep thoughts" or "bromides"? I'm sure there's a name, but the one that just came to my mind is "thinkables". Here's one I just found while going through her cluttered room that I like:

Watch your thoughts-

they become words;

Watch your words-

they become actions;

Watch your actions-

they become habits;

Watch your habits-

they become character;

Watch your character-

for it becomes your destiny.
