Oh yeah, please keep your personal life out of your professional life. Too many people at my agency bring all their problems to work and don't do what they are there to do: work. Many people get passed over for promotions because of this kind of thing.
I've also learned a trick to keep me out later on the weekends since I am used to getting up by 6 every day~~drink lotsa Red Bull when you are out, it will give you a boost
