Consider two pitches for a product:
“I have this incredible product. It’s fun, exciting, and you can spend hours everyday enjoying it. Better yet, it’s changing with the times and you really have to see how cool it is now!”
Or:
“Well, this product used to be great, but now it’s boring. The people producing it have disregarded all that is tried and true about the world. Basically, everything is wrong with it now!”
If those were the two pitches for the product, which one — especially if you heard it day in, day out from almost everyone who talks about the product — would be more likely to convince you to spend your money?
