It's an ongoing frustration to me that many friends I talk into joining then despair that they haven't seen immediate results. As in, after 1 to 3 days. I made zero dollars and zero cents for my entire first month, if you'll recall. 

It's like anything else, you have to play to win. Sure, sometimes it gets really lean. Dire, even. But then other times it surges. The thing is, you need to have already stuck at it and become established to benefit from those surges. 

I wish I knew how to convince them to take a longer view of things. One year is not a significant time investment to go from $0 USD per post to (currently) $200-$300 USD. People just get discouraged easily and quit. The successful few are just the stubborn ones who kept at it.
