I think you've hit the nail on it's head. That one should just use this as a blog platform, and should enjoy the practice of writing and sharing their stories. The earnings will follow, I'm sure. The moment someone gets into this with only the earnings in mind, I guess that's when they lose steam, become impatient, and quit.

So lets enjoy writing...and leave the rest to hard work, patience, and a little bit to destiny too :)
