Lucky direction (facing the desk)

Hi, I am eager to know what is my lucky direction to setup a desktop for an optimal creative and work success energy?
My birth year is 1981, which says that I am a rooster with a Kua number 1.
So here is the confusion: this site says that my lucky dir's are NE, S, W and unlucky - E and N, whereas other chineese/feng-shui sites note quite the opposite being true... ie.: lucky dir's being Southeast, East, South and North.

So what's the deal about it and which is the true direction for success in this case?
