Someone once told me that at the end of the day she'd ask her son how dirty his feet were. If he responded "really dirty!" she'd respond back "then you must have had a really great day!" This is a philosophy I immediately adopted.
Sometimes (or quite often, depending on who you are) it can do you a world of good to kick off your shoes and feel the squishy ground beneath you. Personally, when my bare feet slide across the grass I not only feel connected to the earth I love, but I am also washed over by a sense of liveliness, freedom and playfulness. It reminds me not to take life so seriously....and that's exactly the message I have to pass on today.
