Renee Zellweger is setting a New Year's Resolution to manage her love life better in 2007. Zellweger has spent 2006 single after a disastrous previous year in which she briefly married country star Kenny Chesney before the union collapsed after just four months. Next year the actress wants to try dating again - and do it properly. She tells the Chicago Sun-Times, "(My New Year's Resolution is) To concentrate on doing a better job of managing my personal life. To do lots of cooking and to focus on my cat!''
