People sometimes ask me, "Why do you bother with all this trivial stuff?"
Simple - quantity has a quality all of its own (as Stalin used to say).
What I mean by that is on their own, small problems are just that - small problems. However, when you add them all up, they become a big problem. If you take care of the little problems, one by one, you stop the entire place from turning into a dump. Just look at the bedroom of your average teenager - if they go for a week without picking up their dirty clothes, throwing out their rubbish, putting clean clothes away and taking any plates and glasses back to the kitchen, it quickly becomes an absolute disaster area.
I don't want my suburb to turn into the equivalent of a teenager's bedroom, so I pay attention to the small stuff. Look after the pennies and the pounds will take care of themselves.
