I was thinking that once someone becomes a master that there would be other levels of things that can happen, such as planting corn to grow or a potato patch, pumpkins wheat or even a rice field. A master farmer could fish for squid, lobster, mussels, shark even.Perhaps make use of the coconut shells for bowls or pots or other tools.A master builder should be able to utilize the wood from the wood pile and make other things like a wheelbarrow to carry or move things in.I have a lot more but I don't have room for all of it.
