Hmm.  It's that time of year when I resolve to make myself a better person.  Last year I resolved to actually finish all the books for my book group which I did, sometime moaning like a small child through the entire tome.  The year before I resolved to try a new recipe every week.  Which I sort of did but it's not always practical.
So this year I was thinking of having a screen free day once a week (obviously, not counting work).  BUT  I don't think I can do it.  No computer, email, TV or cinema.  I am not that strong! Just do the eating less and taking more excercise as usual I suppose.  Sigh!  
Maybe I should read Proust of War and Peace or something but I'm not convinced it will improve me.
Good luck with your resolutions whatever they are.
