If you are a newbie not too sure of your level of interest or ability, or someone nursing along a lot of physical disabilities, then the best goal is to just pace yourself so you stay comfortable. A biofeedback goal.
As an x climber type I like some kind of elegant route that follows natural features, prefered to be challenging. less logical ideas like crossing a continent feel contrived comparatively, though I'm still up for it.
Too much goal affects the experience, and visa versa.
