Congruency helps a ton, unless you’re deranged and actually want to make someone accept an incongruency. (which works wonderfully to create slaves - cults and cult like organizations know that if they can someone to accept enough things which don’t make sense, they’ll have a mushy mind to push around)
Congruency comes with practice. With being.
I’m sure you were an astronaut as a child. For a week or a day. But it is what you pretend to be for years that you “are now”.
All reality comes from make believe. We become what we practice preaching and being, it’s as simple as that.
