Glaciers move slow. So slow that without proof it would be hard to tell that they are even moving.
But glaciers are colossal; carving walls and creating unequivocal beauty - a result of their mass, direction and relentlessness. In fact, their creations are only possible because of this.
When it your turn to do something big, something worthwhile … there is no need to move fast. Instead, try moving like a glacier. Be persistent and use force day in and day out.
