I decided that in 2011 I'm going to train one new behavior a month - per dog. This should be interesting. Might be simple, might be complex. With my training skills I'm guessing simple will win out most months. But who knows, maybe by next November or so I'll feel like trying something challenging.
I'm also trying to figure out how to something similar with knitting. One new pattern a month? A new yarn a month? A new technique? Maybe just finish a WIP every month!
