I did something like that for 2008.
For 2008, my only goal was "be happy"
So, be happy at work
at home
when something isn't the way I want it to be
and when it is
and so on and so on.
I have been AMAZED how easy it is to be happy when nothing is the way you want it to be!
It's absolutely wonderful.
It has forced me to not accept external excuses for anything.
So now if I'm "not happy", I have to look at what I'm saying or imagining.
Once I know what it is, it's usually something completely ridiculous that I can easily get rid of.
And then...I'm happy again!

2008 so far has been the best year of my life!
