Make your resolutions. It's almost 2011.
I'm planning on posting mine on this blog once I figure out what they are because once you make a public statement of them, they become harder to break. It's all about the mental game. Make your resolutions and tell people about them so they can either keep you accountable or you can psychologically feel more committed to them.
If you're like me, your first thought was probably that sharing your resolutions with others will just make you feel more guilty when you break them--but at least you'll be able to say you tried if that ends up being the case. Don't let the fear of failure (or the social pressure of the fear of failure) stop you from making necessary and/or desirable change in your life. And maybe if your goals are measurable, specific, and realistic you'll actually be successful! Let's work on coming up with a few good ones and sticking to them.
