Equilibrium

As the years go by, I am convinced more each day that we are part of a system that has an equilibrium.
That must be why we don't always win all the time.
It is just the scale balancing out when I lose out on something precious. It must be someone else's turn to get it. Not my turn yet.
When I get a huge unexpected discount on something at the store, it must be that equilibrium.
An inbalance occurs when I keep more to myself than I'm supposed to, but someway somehow, equilibrium gets restored. Either through voluntary acts or it just happens
Somethings we just can't explain, but this is my basic visualization of how things work around me.

According to edictionary.com, equilibrium is "equal balance between any powers, influences, etc.; equality of effect."

A friend of mine recently agreed with me on my basic model but didn't like it as much anymore when I added that God is the one maintaining that equilibrium.

I'd like to know the most fundamental model you have, that expresses your view of how things work around you.
