10 laws of boundaries-good read

I found this pdf online, but I don't know who to give credit to.  It sounds like a student at Cornell wrote a paper on boundaries.  I think I will use this as the basis of creating some new boundaries of my own.  Having weak boundaries causes a lot of unnecessary pain.
