I don't agree. I know your opinion differs but I'd consider someone who banks thousands of leads a day and has made it defensible for the foreseeable future a success.
Success, for me at least, is freedom. Worrying about how long my latest campaign or traffic source is going to last is not freedom to me.
It's all well and good raking in a few thousand dollars a day but it's a lot better when you know it's going to last.
