that is within your own grasp. You will have to retrain your mind so to speak. I think though the momment you want for nothing is the day you are no longer in form so you may be asking to die in a pretty manner...but I could very well be wrong about this. But in what I have observed even the people that say that want nothing are only decieving themselves as they will become gurus and such. So they want something or they would not hold gatherings even if its that they want others to not want nothing or obtain what they have...this is just my opinion though.
