First of all, there's no the best way to make money online, there are just "good enough" ways. Read below for more info. Also, follow just one person and stop reading forums.
Secondly, don't buy a product that promises millions without any work and dont tell you what you will get inside they are scams. If you want REAL working system, Jason Fladlien (he's ethical one of the best marketers around) released his new coachin program for insanely low price and I'm in. It costs just $97 whats insane.
Here are a couple of things that I recommend you do:
1. Provide a service. This can be a very profitable thing and you can start profiting from this today. What can you do? If you have some skills, like creating graphics, writing articles you can do very well. Just post your service to warrior forum or to other forums in IM niche. Or to fiverr.com
Or, you can set up a simple site (you can even use blogger.com if you want) and provide a service there. Then just put a link to your site in your sig where you provide your services and make a lot of posts in this forum. 50 posts should be enough and you should get a couple of clients.
Another powerful service that you can offer is turning articles into videos. Not many people do this, everyone is writing articles, that's why it's so profitable.
2. Promote CPA offers. If you're in UK or US, here's what you do: you find a CPA (cost per action offer, where someone completes a simple form, like put their name and email and you get $1-$25) and then go out there. First of all, print some flyers and put your domain that redirects to your offer. I recommend you choose an offer that offers something for free, like an Ipad.
If you go to a school or a college, just tell your friends they can win this. You can also tell them you'll do something for them if you know what I mean.
If you're mum or dad is working as a receptionist or so, tell them to give these flyers to their clients
