Recently read this quote in one random blogpost that I stumbled upon surfing. Sorry forgot to save the link.
Loved it. As most of my work time, now a day are saturated with the words like, model, training etc., so this quote stuck a nerve.
Reading and experience train your model of the world. And even if you forget the experience or what you read, its effect on your model of the world persists. Your mind is like a compiled program you’ve lost the source of. It works, but you don’t know why. – Paul Graham
