Advertising design is competitive and difficult to master.

Advertising is the most lucrative niche in design.  It's also the most competitive and difficult to master. Why do you think this is true?

     I believe that advertising design is competitive and difficult to master because the design needs to hit the part of your brain that controls your subconscious desires. This is difficult because you need to really KNOW your targeted audience. You need to know exactly what they want. Do they want a sexy half naked man that's covered in soot or do they want Sponge Bob Square Pants? What is going to make that audience say "ooohhhhww, I want that"? Lets take salad dressing for an example, now I am a 25 year old, married, female with 3 kids. So to target the audience that I would fall into, you would use the sexy half naked man. Now if your target audience is 5 year olds, I would advise to use Sponge Bob. Getting inside all those brains is going to be difficult.
