I subscribe to a daily quote from the Happiness Project. This was today's....
"After all, a vacation is not a matter of place or time. We can take a wonderful vacation in spirit, even though we are obliged to stay at home, if we will only drop our burdens from our minds for a while. But no amount of travel will give us rest and recreation if we carry our work and worries with us."
-Laura Ingalls Wilder, essay September 1919
Teachers are bad about working all summer on professional development, classroom organization, Pinterest-ing, etc. Make sure you take a break at some point over summer BREAK! :-)
