Confirmation or tips?

Hello there I am Thom and this is my first Post here on Warrior Forum!
So a while back I clicked on an add that said: Get $4k a month working at home! Now I'm not stupid enough to actually belive that ofc. Though I had seen so many of these add's I just wanted to click on one for a change.
I immediately knew this would not be something I was gonna buy, but that doesn't mean It can't be interesting. I figured if so many people can afford to place add's then there has to be some money in the business. I belive the add was from an internet marketing guru who would teach you all kinds of stuff to make money if you would pay him $500 a month. And it had a lot of subscribers too! So I started research to see and I got to this site pretty easily since it's high ranked.
Now this is the First site that really got me interested! It seems this could actually work! So now, a month or so later, I've read through a LOAD of stuff on here and I've made my conclusion.
I can keep researching for more weeks or months but in the end I would probably gain 10Ã-- the knowlege if I would just start on a site and see what happens. Since I have so many question's it would be better to have an on-going site so I just figure out most of them.
I know this is gonna be hard work for a long while but I know I should be clever enough to get this to work and I have a LOAD of time on my hands. Like 14hours a day if needed.

So I want to start off but I'm getting stuck. This is where I need some help I think. I want my first site to make profit. I don't really care how much as long as it is more than I pay to keep it up. So I want to start an mini-niche site using clickbank. I figured I just start by putting up a review site like you guys suggest often on this forum. Then start making the articles and posting them on high ranked sites. This should keep me busy for a while, ill just see what happens after that. But here is the main problem.

I couldnt find any page in here that gave me enough information about how you guys find a proper niche. I tried using AdWords but before you can use that you need to know what kind of niches are the ones you are looking for. I know about the low competition and the high searches but I know absolutely nothing about what kind of niche would actually make no money and what kind would have people who are interested in buying.

So my question is: Can someone help me to find 1 decent niche that would be good to start my first site? Just to get me going, to get experience and so I can finally really understand all the post around here. And maybe someone who can confirm my plan on how Im about to begin.

I would really appreciate any answer, even if I can't use it!

That being said I want to add that I really like this forum and I can see how it will hopefully allow me to get a business going just like many others around here. You guys are great!

PS: Sorry for the long post for a relitively short question
PPS: I know you guys probably wont tell me you "big secret" on finding niches. And I'm not asking for it. I just want 1 niche that's decent so I can start. So any tips would be a lifesaver! Maybe something like how you found your first niche that made more profits than loosing money.
