dS = kB d(ln Ω)
Entropy in a microscopic sense is defined as the number of states in a system which are readily available to be occupied. An example of this is the number of locations you could place a molecule in a room of volume V, which clearly increases as the volume increases.
In a macroscopic sense, entropy is the parameter of a system which identifies the direction towards lowest energy. Where even time is not theoretically bound to move in one direction, entropy is. There is no escaping the tendency towards a lower energy state, towards the heat death of the universe.
So we are all subjects of entropy. We cannot escape it from within a universe in which particles mix and diffuse through the system, occupying more probable microstate than the previous position. Therefore, take the moment you have now in the present to appreciate the state of the universe around you, since it will never be that way ever again.
