One cannot change this all in a moment, but one can at least change one’s own habits, and from time to time one can even, if one jeers loudly enough, send some worn-out and useless phrase – some jackboot, Achilles’ heel, hotbed, melting pot, acid test, veritable inferno or other lump of verbal refuse – into the dustbin where it belongs.
Well this has answered my question from earlier! The way we can really bring about change is to firstly be aware of what's going on, then put a conscious effort into stopping it whenever you can.
