Here is what I did:
I went onto Google Trends and looked to see what was hot at the moment. Once I found a good topic I jumped on it. I threw a post up on one of my websites, wrote one article, submitted blog post to digg, and submitted an answer to Yahoo Answers. Yes it was that easy! I instantly started seeing the traffic roll in since both my digg post and Yahoo Answers post got ranked on the first page very quickly. I used CPALead to generate a gateway for my content which is how I made my money.
The whole process took me no longer than an hour. Going in I wasn't even sure if it would work. Although I am happy for my success, I think the greatest lesson this has taught me is just to take action! I realized I need to stop over analyzing every single niche decision and whether or not it will work and just try it out myself.
