Consume Product

I've been getting into more and more depraved shit becuase of my recent relapsing. I don't really know what to do because Its like my mind just keeps slipping into that cavern over and over again and It leaves me with little to no self control. I've heard a lot about addiction and quitting from you guys and one of the things you often reccomend is being on a mission. I don't really know what it's like to be that determined and focused to be honest. There's not a lot of times where it was just me and a goal I've set, more like a goal someone else has set that I've helped along with. What do you guys do when you need to achieve your goals?
