Can someone analyze this

I have no idea what it means
its from the poem substance, Shadow, and Spirit

You had better go where fate leads.
Drift on the stream of infinite flux
Without joy, without fear:
When you must go-then go
And make a little fuss as you can.

The key to that is "infinite flux". That means always changing. Life never stays the same; so deal realistically with the changes as they come. Some are going to be good, some bad.... don't make a big to-do about either because it is going to change again.
