“The sun, with all those planets revolving around it and dependent on it, can still ripen a bunch of grapes as if it had nothing else in the universe to do.” – Galileo
Everything is part of a grand design with purposes both great and small but all significant to the function of the whole. We are part of that design also and with significant purpose as well. You were called to do great things but not at the expense of the small things.
It’s a wonderful thing to strive to change the world for the better but don’t forget to wave and say hello to your neighbor as though you had nothing else in the universe to do because it matters just as much.
