I think this is kind of like asking, "What's worth spending your hard-earned cash on?"
I would rather travel the world and be poorer (ie, I am happy to spend my cash on travel rather than investing it in something that might make me richer in future).
But I wouldn't sacrifice career opportunities to travel the world... you know, like I've got a good job I don't hate and the chance to build a nice career if I keep my nose to the grindstone, OR I can quit my job and backpack around the world picking up a little cash here and there and living with the locals... nope, I'm keeping the job and reserving travel for vacations.
