Can entropy be applied to our day to day lives?
I have been reading about entropy in physics and am wondering if there are any applications of it outside of physics and in social systems.

ABSOLUTELY!
See https://jick.net/skept/Therm/ and https://jick.net/skept/Therm/Therm-pres.pdf
The first step is to avoid the rabbit-hole of Classical Thermodynamics and get up to speed with Statistical Mechanics a la Boltzmann, which gives a straightforward definition of what entropy is: namely, the logarithm of the number of different ways you can "divvy up" a given supply of some conserved quantity like energy or money.
Stat Mech has immediate implications for the distribution of populated states of different energy in thermal equilibrium -- or the distribution of wealth in a closed, equilibrated system where financial transactions occur randomly. Both yield an exponentially decaying population as a function of energy/wealth. You may consider the postulate of random financial transactions to be ridiculous, but then why is the actual distribution of annual incomes almost a perfect Boltzmann distribution except at the bottom (where social assistance "flattens the curve" a bit) and at the top (where nonrandom cheating extends the tail out towards infinity)?
If you master the simple notion of "more ways means higher probability", a huge number of otherwise mysterious phenomena will make perfect sense to you.
