For all my stressing and fussing before any impending trip, I always seem to abandon all hope just before the start, chuck out my plans and proceed with the, "Ahh let's just go and see what happens." method of embarkation.
Things always seem to turn out well in the end.
Yet, if I decide to just go with the flow from the beginning - I'll spend most of the trip fretting about the lack of prepwork.
Never pronounce something as useless, even if you don't think you're actually using it.
It's all in the process, init.
