If you wanted to start selling online business what would you like to know?

I am an Internet business owner, and when I started everyone was in it to get my money. I wowed to change that, so I am working on putting bunch of free tutorials for people who are just starting out. I want to know what would you like to know, if you were just starting out. I am not top seller on eBay and I am not making millions, just and average person making my living online. I have been selling successfully online for the past year or so. a lot of resources are available to people for free, but most people just do not know how to find them and use them. Thanks for your response.
