I was reading Sevenless's guide today and I found a curios that gave me 6k LP. Before the study time finishes, I want to know if it's a good idea spending it on Yeomandry ( My leather keeps getting stolen

) or go with boat building and level 15 exploring. I'm level 7 exploring right now and don't have enough curios to learn all of them. Which is the better choice? Also, I probably can only choose Yeomandry or the other two considering that it takes 10lp to get more squares which is what I will be doing.
