Here's some great advice from a woman who inspires me, Meg Hourihan:
I'd keep bottles of wine and treasure jars of jam for so long they'd be
no good once I got around to using them. I decided life was too short
and that it was important to use the good stuff. And now I do, mostly.
I saved a beautiful birthday gift of 1989 Laurent-Perrier Champagne too
long (no situation ever seemed good enough to justify its drinking) and
when I opened it, it was passed and I was so sad. It was just the kick
in the pants I needed to remember to use the good stuff.
