How do you let go of attachment ? question to all

Did you know the origin of suffering is attachment, Often we recognize our attachments are unhealthy yet we suffer because we have such a disillusion idea of who and what we should be and have. I am on a course to let go of all of my attachments and enter each relationship I have with the realistic idea that at some point it will end. Nothing is forever and holding on to our wants, needs, people we love who do not love us back any longer, fears, worries, and possessions lead us to perpetual misery. I no longer want to long for anything but instead enjoy what is happening around me at all times. I would love suggestions on how others let go of all things and am willing to re post for your help?
