What's the "default" setting in life?
While this may surprise many, I'd argue that the default actually should be described with words like... dirty, mean, messy, ugly, unhealthy, unhappy, yucky, and the like.
I say so because too often people (or even myself) take (good) things for granted.
A city doesn't stay clean by itself. Sanitary workers work hard to take away the trash and clean up the roads.
A person doesn't look amazing simply by breathing and lying around. That beautiful person is pretty usually because s/he has worked for it in some way, such as exercising, choosing healthy foods to eat, and getting some nice accessories (including make-up and clothing) to wear. (Of course, I understand that some may be born pretty... but that's another story... This is written with the average person in mind.)
A food doesn't become delicious and get to the table by accident. There are actually people who take the time to cook to have them that way.
So STOP. Stop believing that those people in uniforms and standing next to garbage trucks don't worth a smile or a thanks from you. Stop believing that people should appear to be pretty by default. Stop believing that a smudge on the floor cancels out the fact that the rest of the floor is not covered by smudges.
START. Start understanding that you owe a non-smelly household and neighborhood to those that pick up the trash from you. Start understanding that people will look even more wonderful if you compliment them, yes, even when they have no make-up on. Start understanding that you can notice the smudge only because the rest of the floor is relatively clean and that someone is (actively/passively) waiting to be thanked.
Taking on this kind of viewpoint on the default of life changes everything.
Life becomes more worthwhile more easily.
