The way (and perhaps most students around the world) I was taught QM is very weird. There is no intuitive explanations or understanding. Instead we were given a recipe on how to quantize a classical theory, which is based on the rule of transforming all quantities to operators, and that Poisson bracket is transformed to a commutator.

For me it seems like a big secret remains out there, it's just hard for me to believe that this is the way our world behaves without further intuitive explanations. But also a few years of searching didn't help, I found nothing. Does anyone know something? I'm not talking about "understanding QM", all I want is a small clue which will take me one step deeper to understand this canonical quantization procedure.
