Remember (per our current scientific understanding), entropy goes in one direction from orderly to chaotic. No matter what you do, the total entropy goes up, and doing nothing does increase the total entropy less.
However, instead of letting that fact let you down, it is possible to do things that locally reduce entropy and make things more ordered in your local environment. All this to say, don't focus solely on the inevitable, focus on that which you can control, what you can hope for, and what you can make better for yourself and your world.
