In my case it is not so much self-confidence: I am always overanalyzing and can never decide on things, other than perhaps what to order for breakfast.
Rather, it is more my stubbornness. I want things one way even if it may be wrong. I resist change and nagging. I annoy my parents and doctors. I am often just a cranky old man, LOL!
I have some smarts and it has led to success, and that has bred confidence. Until some bright whipper-snapper comes along and puts me to shame. I just cannot keep up with these youths, and must rely on experience. But once they learn, they no longer need a dinosaur like me.
Yet someday I will be replaced by AI. And so will they. So we will both be on welfare. Let us hope we find cheap energy and robots make lots of food and goods cheaply, so all can be sustained without much money.
Yet then we will all become fat, lazy, stop studying, and eventually join the human zoological park sustained by our robot caretakers.
