Help choosing an Impossible Goal

I’m indulging in a bit of confusion and indecision regarding my impossible goal. I want to lose 20lbs, really get my coaching practice off the ground-make my first 100K and stop over drinking. I know Brooke says to choose one and the one that encompasses the others but I’m having a hard time distinguishing what that is and what to choose. I also know that “it technically doesn’t matter” which I choose but I really want to achieve all of those things in 2021 and they all seem impossible right now.
