You do not need any business experience to get started in affiliate marketing. All you need is the drive to succeed.
As long as you have the drive then anything is possible. You just need to put your mind to it. In the affiliate online business that is what matters most.
Now you need to start out by doing something like building affiliate sites that will help other people out and then presell them to buy the affiliate product you are promoting.
It really is that simple. You should pick a product on a topic that you at least find interesting enough to learn about.
