I found it one of the easier parts... I started college for business management. Honestly marketing is simple and that side are simple...to me.
Then again the rest of it is hard. I am kinda wired backwards, I lack all organization, yet I could structure and organize a business for someone outright...but then they have to take it because if I keep it too long it will explode LOL.
I designed a self cleaning carpet and marketed it in my marketing classes lol...its actually kinda interesting...
EDIT: btw, take psychology classes. Marketing and advertising is all about reading what is already there, as well as creating new things to place there(we are speaking in peoples heads). Manipulation is one of the easiest feats in the world with all the sheeple out there.
