Body-You will say anything to get what it wants, including “We don’t have time.” I’m calling it Body-You but, at least for me, it’s really a collection of parts of my mind that are against the action.
As for the “lying”, Body-You knows it is not a lie but doesn’t care. If You believes You is lying, Body-You is more than happy to use that as yet another excuse.
Personally I call these two people the "Planner" and the "Doer". Neither of them start out with bad intentions, but only one of them has to actually do things in the present moment, so resentment can definitely build up between the two.
