You can't keep thinking about a future vision as the old version of you, and expect to figure out how to get there. So if you want to go to the other reality, then you've got to stop thinking about it so logically, and you've got to stop feeding into the logic and the doubts of this version of you, because all that's doing is it's trying to keep you stuck here. This doesn't mean that you're going to just set this big goal and not feel doubt. In fact, if you've set a goal and you're feeling doubt, it's just a sign that that goal is really like exciting goal that's going to stretch you. All you have to do is stop taking the doubt so seriously, realize it's the logical aspect of you trying to make sense of something that it can't make sense of, and just make peace with that.
