Okay, so in spite of all protests to the contrary, you know everything. Nothing anyone else says will make you doubt your belief in how much you know – how much more informed, intuitive, and perceptive you are than everyone else.
On the off chance that’s true (and maybe for one person out there, it actually is – but the numbers would suggest one person only), then imagine how boring it is. There’s no surprise. There’s no need to better yourself. There’s no search for the unknown. Because there is no unknown.
And when there is no unknown, everything just seems the same.
