The Right Mindset regarding "Addiction"

I read something somewhere, where it was like, every time you restart, think of it as your addiction is already done and over with. Like, from that day forward, think of it as you're forever free from that addiction. Because honestly, what time period determines that you're finally free from addiction? You honestly can never know, because we can't discern the future and see where we end up 3 months or 3 years from now. So just live everyday like it's already behind you, because it is, if you're making efforts to move beyond it.
