I've been thinking a lot about the ability to appreciate life's highs and lows.
I've also been thinking this poem gets even better with about the fifteenth re-reading.
(have I mentioned that I've had some thinking time on my hands lately?)
Your joy is your sorrow unmasked.
The self-same well from which your laughter rises was oftentimes filled with your tears...
the deeper that sorrow carves into your being,
the more joy you can contain.
