One of my secret heroes, Hildegard von Bingen, said the following. I do think we are the navigator of our own ship ... but this still resonates in the middle part of my heart ... in spite of what I think:
"Listen: there was once a King sitting on his throne. Around him stood great and wonderfully beautiful columns ornamented with ivory, bearing the banners of the King with great honour. Then it pleased the King to raise a small feather from the ground and he commanded it to fly. The feather flew, not because of anything in itself but because the air bore it along. Thus am I a feather on the breath of God.”
Because you can strive and strive and strive but sometimes it feels like it doesn't matter. Things just go. Life just unfolds.
