If life is a giant river, deep and wide and long and moving, I don’t want to ride it on a jet ski. That’d be too noisy, and too fast. And I don’t want a cruise ship with extra little boats hanging from it in case something goes wrong. And I don’t want a submarine to lurk around in. And I don’t want a barge to haul tons of crap around with. If life is a river, just give me a raft, and that will do fine. On a raft, I’ll cruise at whatever speed the river wants me to, and whichever way I look, I’ll see beyond my vessel.
