My two favorite quotes right now.
"The days are long but the years are short." - John Leguizamo (InStyle Magazine, July 2005, via Metrodad)
"everyone is as happy as they choose to be" - Abraham Lincoln, paraphrased by my mom. (Okay, before someone gets persnickety, the quote is really: "Most people are about as happy as they make up their minds to be." I like my mom's version better.)
