Well I actually do Marketing brand new at it and i might say its working very well for me. Its all residual so i only have to make the sell once. Its the freedom that does it for me, like being my own boss. So marketing is what i'm doing.
I do a ton of stuff. My main business builds mobile apps and does text message marketing, but all through online marketing/building. I also am doing affiliate marketing and just started writing posts for others.
