I think someone else said it here, but it bears repeating. Detachment happens in your mind, not in your actions. Once it's firmly in your head, your actions naturally follow.
Remniscint of this is a passage from the Bible:
Luke 6:43-45
"No good tree bears bad fruit, nor does a bad tree bear good fruit. Each tree is recognized by its own fruit. People do not pick figs from thornbushes, or grapes from briers. The good man brings good things out of the good stored up in his heart, and the evil man brings evil things out of the evil stored up in his heart. For out of the overflow of his heart his mouth speaks." [My Emphasis]
If you want to change the fruit, you've first got to change the root.
And it most definately is a process. No shortcuts here.
