Actually not a whole lot, can be done in an afternoon, few hours if you are doing absolutely nothing else. It actually speeds up quite a bit with every skill point, though it isn't perfect like I mentioned, so be careful what you pick. The xp requirements for fishing are quite rough, though maybe the second pond fares better, I haven't gotten around to checking it yet, but I imagine that is the reason It took way longer than the woodcutting. I wonder what the girls were doing in the literal in game months I spent grinding tho.
