I've seen too much & done too little

My one main pleasure in life is traveling and I've been fortunate to visit many remarkable places around the world. Yet, what have I really gained fr0m all of this wandering? Has it resoloved any of the depression that envelopes my heart or has it merely been a momentary distraction -- like going to a movie and being trasnported out of my corporeal self into a fantasy world? In the end, I wind up back here in the same place I started, quite a bit poorer and always wishing I had done more.
