Sorry, I have zero idea where you are getting that fear stuff. I am aiming for realistic - which may scare some but not me.
How can you be “realistic” about what you don’t know? You have to plug something into that unknown space. Usually we color it with either a pessimistic view of a worst-case scenario or a more positive view and underlying both is either hope, which is confidence expectation of good, and faith, or something more pessimistic which some call “realistic” but in fact is not really more realistic. There’s much to be said that our paradigms actually have a lot to do with shaping the unknowns in our future.
