Once I spoke to a psychic, and he told me that at age eight, I experienced something that had been very significant in my life. I thought about it for a week, and could only remember having decided to understand the world around me to prove to the bullies they did not belong in it. Then later I heard Nassim Haramein talk about an important event in his life at age eight, and just now, Michio Kaku told Lex Fridman something similar.
But the meaning of life was my main quest for decades, until it became clear that just learning about the meaning of the universe means nothing if you are not also living that meaning.
