the truth is if you keep doing it for the money and it's not rewarding then you get really sad and discouraged, for instance, i have been posting for some months now and i have no tangible monetary reward to show for it because it looks like no one knows that someone like me exist here, someone advised me sometime ago to drop comments that i will get followed or noticed but it seem after that comment or conversation, that is the end, they do not remember you anymore... so somehow taking my mind of the money for sometime at least helps to keep my sanity.
