I started with my own web directory a couple years ago and although I made a few hunred dollars, I didn't like where the industry was headed....(selling PR), so I shutup shop and kept on searching for an idea.
I then came across the Warrior Forum and thats where I soon began to see the potential of list building...and I've never looked back.
Why? You ask.....I just CANT work for a boss for the next 40 years....it's too depressing...and I love the Internet so much, I wouldn't be happier working anywhere else.
