I think there's more money in porn, but alot harder to promote. non-porn and porn both have advantages and disadvantages.
the best for me is whatever give a ROI in short amount of time... niche sites with adsense or affiliate links...
lol the bets is now not legal in USA oh well... oh and if were talking about the money$$ then I hear pill are big...
Do anything and everything you're good at. I rely on several income streams, too much risk with only one.
The truth and it'll usually take a lot of experimenting to find which one is right for you. Unless you are really confident and talented in one area, then you're set up!
Couldn't have put it better myself. Write a list of all the things that you are interested in and think how you can make money from it. Every 2 weeks start working on a different item from your list and soon them income streams will become a river.
Echoing and expanding, the best business is something that you have interest in. If you don't like what you do, you won't have the ability to grow/learn and stick through any tough times that may come. If you have interest in the business subject matter, everything will fall in place, including the knowledge and the drive to push it forward.
