The writer of this has cleverly depicted the anti-sad references in this piece as real places, tangible and therefore reachable goals that lie on the banks of sad-no-more, depicted as another real thing, a river or stream. What he or she is trying to say is that to be sad-no-more you have to go through or experience all the places on the way.

It can mean anything you want it to mean, thatís one of the great things about reading poetry, you can use your own meaning or interpretation . Sometimes you can change that meaning or interpretation to fit your mood, I guess what Iím saying is that poems are open to your interpretation, they mean what you think they mean and sometimes mean different things to different people.
Hope you understand what I mean
Yes, I admit your general rule. That every poet is a fool:
But I myself may serve to show it. That every fool is not a poet.
