Two things cannot occupy the same space, so you have to empty it before you can fill it. You have to empty your mind of thoughts before you can have new ones. You have to empty your physical space of junk before you can have better stuff. You have to free up your time before you can spend it on what you want. You have to free up money that you’re currently spending if you want to spend it on other stuff. So, the initial goal is to get to zero.
