Life spiral

In numerous cultures, the spiral is a life symbol of one kind or another. From time to time I would wonder about this. I never came to a solution that I thought was anywhere near authoritative.
But I did happen on an idea I liked.

Take out a sheet of paper and a pencil. Pick a point and draw a straight line in any direction. Stop at some point. This never seemed a sensible diagram of the path of a human life.

Now, draw a spiral starting from its outside limit and moving toward its resolution point. There's not the same certainty of conclusion along the spiral as along the straight line. Even more, as you  move along the spiral, you are, in fact, always moving away from your final destination just as you are moving toward it.

To me, this is a much more satisfying image of a life.
