N+K wide open on the edge holds off the queen, other lessons learned

Here I saw a great opportunity to sacrifice a bishop and decimate all the king side pawns of my worthy opponent and take that rook. http://en.lichess.org/pDDe8s8a#25 I like how it turned out, but I did not entirely expect how nicely my one knight would defend my king. The Knight's box of defense was just perfectly suited for the situation. I admit the sound defense here was a bit of luck: http://en.lichess.org/pDDe8s8a#35 Once we got to endgame and I had a strong pawn majority with several passed pawns (is it 2 or 3?) I thought I had it in the bag. http://en.lichess.org/pDDe8s8a#57 Big lesson learned here, I think: having several passed pawns is not that much of an advantage. Not that much better than a single passed pawn. I made some mistakes here that jeopardized my lead. Finally, after a long string of mistakes on both sides I barely eeked it out in the end: http://en.lichess.org/pDDe8s8a#105 This was an enjoyable game. Thanks Freddy11.

I think my biggest mistake in the endgame stemmed from impatience and being overly confident with my majority..
