Off the top of the dome

So I was thinking: Why dont i create a blog, and maybe generate some income off of it? yeah, it wasn't just as simple as that, but then again if you put a little bit of hard work and concentration into it, you can achieve most things. Yes, I know is sounds corny, but is it false? Anyways, creating the blog was easy, really just click a few buttons and fill in a few blanks. But then i got to the part where i had to find adds which should generate my income of course. My first thought: Google AdSense. But wtf? Too many complications, and way too few direct answers. And just to make all this a little bit harder, I'm not even 18 yet ! why can't young people, under the age of 18, generate their own money online? I know I'm not legally an adult, but come on, I can handle my own money ! It just seems unfair. But what do I know...
