In Glitch, how can I see quickly how many skills I have learned

Invest some time learning Animal Kinship. The higher levels of this skill allow you to squeeze more grain from chickens, not to mention squeezing the same chicken multiple times. Animal Kinship 6 and 7 also raise the chance that you'll get bonus goodies and super harvests to a level where you see them regularly.
