This is how you tackle your New Year's resolutions:

1) Set a goal (World's largest snowball fight).

2) Take steps towards that goal (order truck loads of snow delievered to Seattle Center, invite people to participate, and communicate your intentions to the Guinness Book of World Records).

3) Follow through (start throwing snowballs)!
