The little changes you make to your life, and those who are around you, will have a huge knock on to your wider community. For instannce, somebody paid for CCTV in our block of flats, and somebody mops the floor and fixes the lights.
It means the stairs are safer, cleaner and it improves the well/being of everybody in the block. Don’t fight a battle that can never be won, see what you can change in the world around you and the world you wish to see will develop before your eyes.
