So one of the hallmarks of narcissism is grandiose fantasy that doesn't correspond to reality.
You might think “Wait, don't those people have a lot of shame to carry already? Why push themselves even further to the edge?”
But the problem with realistic plans is you have to deal with realistic expectations of yourself. But bad plans can always be the fault of the abstracts, the banking system, the military industry, the capitalism, the human nature.
The goal is not to make the fantasy become reality. The goal is to escape reality.
