A pithy thought to mull over mulled cider:
Do you ever have difficulty figuring out if a question is rhetorical or not?
Seriously though, there is one saying which never fails to confuse me;
"That which does not kill me, makes me stronger."
Where do bubble-baths fit in? They don't really do either. Or chocolate chip cookies? I propose a change,
"That which does not make me stronger, kills me."
In the respect that if something is not helping you improve, or grow, it is slowly contributing to your downfall.
Boy. I feel smart today. :)
