Hi everyone! Blogging this morning from the beautiful Wilmington, NC airport, preparing to board. I wanted to tell you about something interesting that came to light in the past few days.

The journal Nature reported this week that paintings of hands and animals in seven limestone caves on the Indonesian island of Sulawesi may be the oldest human art yet discovered. It's estimated that the people who did these simple paintings put their mark on the stone walls more than 39,000 years ago.

Since the beginning, human beings have wanted to make their mark in the world, to say "I was here!" I love it that so many of the paintings were outlines of hands. "This is me." Or, "This is my son." Or, This is my mate."

Those artists could have had no idea that we'd be talking about the hands and the animals they painted, more than 39,000 years after they made those simple, but inspired markings.

Likewise, we have no idea how far and wide our simple daily acts may reach and what impact they may have on others. The cave painters could never have predicted that their work would move us in 2014 to reflect on our own lives, and on how we make our own marks on the world.

And their lessons are many. One is that the smallest things can leap and fly across space and time with amazing results. Try to remember that in the little things you do.

Today.
