In an age where marketing schools teach more math than creativity, analysis is everything, and you've got to be able to tell the age of every person buying your product from your office miles away from the nearest store, it's a wonder people get stuff done. Sure, segmenting the market is good, it can even help sell a few units. But what happened to the most basic principle of marketing: just make it good. The product, the ad, anything.

 You can sit all day and wait for the next epiphany to happen and maybe it will come, but in the mean time, i'm going to be spending a lot less time and money than you are and i'm just going to make my product better. Have fun trying to sell something to people who don't want to buy it. I'll be hitting the golf course with the piece of mind that my product make people come to me.
