I don't have to define or measure it. And this does not make it meaningless either. In fact most profound things in life can not be measured. Can you measure how much parents love their child? Can you measure how happy someone is to get a present they wanted? Can you measure how funny a joke is? Measuring everything is a stupid approach to life and things like brain development and human potential for sure are immeasurable but are the most significant.
