I have heard the term "game changer" 5 times this morning, and it is still very early.
I ponder how imprecise our usage of our language is. Every micro change in every product or marketing scheme seems to be a game changer now. Everything we see, do, or want is awesome. We are so filled with crap from people selling us stuff we don't need, we don't often realize how saturated and ridiculous we sound.
I am also to blame, I use terms that have been ground into me by society but I do really try to shape my meaning precisely with my words.
I am hoping to just cause you to think about the things you say. As much as I can respect a teacher or self proclaimed guru etc... when I hear them promote themselves or a product as a "game changer" I can only guarantee to lose the respect I had for them and never look at that product.
Think on your actions and the causes they affect to anything they are attached to.
