how can my personal symbolism be right or wrong? It's like asking someone to logically justify their color preferences

No, your preference is factually wrong! ::eyeroll:: Silly person. Your reasoning for liking 8 and 64 makes sense to me. :)

I don't consider any numbers lucky or unlucky myself, but I definitely have numbers I like or dislike, and there seems to be a system to it but it's not based on anything logical - one number makes me feel good and another feels wrong. It's weird.
