many have answered that as a concept, it is made up. But it is arguably the most real (and important) thing in all of physics (or maybe action, which is also some function dependent on energy). the money comparison is fine, if we have different forms of denominations of money (currency notes (different amounts), gold coins, etc) we have different forms of energy quantas.

Here is a viewpoint to understand - almost everything acts in a way to minimise total system energy. this can be (almost) made valid all the time if you include some probablistic factors. (If we take thermodynamics (which is by definition study of dynamics of energy(and heat, which can be considered as some kind of raw energy), then we include entropy, which is basically finding how many ways can a particular energy can achieved.). This is not a very rigorous way to put it all, but basically all of physics basically works on energy. Forces are basically caused by some kind of gradient in energy.

Zipf’s Law is far more universal than human language, It is almost appears naturally if we start with a few simple conditions - consider a finite total group, and a initial distribution, where different elements have different wights and growth rates of elements is proportional to weights. https://en.wikipedia.org/wiki/Zipf’s_law

well that gives me some soothe

my family is dying and i dont like it, atleast get me on the tracks with them, would not be able to live with the guilt anyway
