Vizilla,
It takes some time man, truly it does. The one thing that is hard is staying focus. You sound a bit like me and I am willing to bet your mind is on a hundred things to try/do to make a buck all the time. Am I right?
If so, thats a failure point. I have been a webmaster/Internet marketer for over 13 years now, but all that time was working for someone else. Once I got on my own I failed at my own projects over and over and over again. I kept trying so many different things and failed. I almost gave up for the 100th time. By failure, I mean I had some sites I was negative cash flow in, some that broke even ( paid the rent ), and some that barely made a profit ( were talking maybe $10 here ).
I wasted a lot of money and time. Then it hit me to focus on a few industries only. After much research I narrowed everything down to 3 industries and I built a few ( a handful ) of new sites in each industry. I used free blogs, squidoo, my own sites, hubpages, etc... After some rough testing of about 3-4 months, I settled on one industry and started to build around that one and only industry.
All the things I failed at before, I could somehow morph into this industry I settled on and I started to use those projects also with my new found niche. Sure, I always wanted to try new things ( new niches ) and got distracted, but I thought to myself this is the last thing I am going to do before I fail again and I pushed through with this one niche I settled on.
What this did was give me a pretty good sized network of sites all somehow related to my niche/industry. They were not all the same sites/style of sites, but it afforded to give me a nice network I could test and bounce things off of. All my failures also provided me a game plan of what not to do, what to improve on, and what to stick with.
My new network didn't do much for me the first 2-3 months it was finished, but it did help get all my sites indexed, ranked, and noticed.
About the 3-4th month I started seeing some income from various things I was doing. Adsense, affiliate offers, links I would sell to others, etc....
Was I rich? No. Am I now? No. Can I live off my network? Yes.
The income I started making was small, but it was mine and it was something that was working. I added more sites to it, tested different things, and improved on it over and over again.. maybe too much.
Now anytime I want to launch a new site, I have a network to back me up on it and the ROI is so much better.
It takes time man, it really does.
