When it is not necessary to change
If you change the way you look at things, the things you look at change.
CHANGE, IF YOU CHANGE THE WAY YOU LOOK AT THINGS
Change means that what was before wasn't perfect. People want things to be better.
CHANGE, CHANGE MEANS THAT WAS BEFORE WASN'T PERFECT
If you're in a bad situation, don't worry it'll change. If you're in a good situation, don't worry it'll change.
