How do create additional income streams?
Is there a process that you use to find new opportunities to get additional income?
If you can build something, do it. There will always be a customer, whether they'll pay well is another question.
If you want to do it the blackhat way, churn and burn. It's the reason why the internet is full of garbage now, why there are millions of blogs that talk and talk but say nothing. Do you like lists? Write those down and catch someone's attention, then backlink other blogs using keywords and SEO. Feed off of each other's client stream, the clients being the soul-drained tube riders that would rather click through a thousand boring pointless lists than talk to the rider next to them. Then find ways to amplify that.
