paying blog

Tweet

I know my question has been posted before but i'm asking all of you to be a little patient with me because I can't find the exact thread that will answer my question. I'm a hopeless newbie who has just recently become interested in the interent and blogging. I would like to know how I can come up with a paying blog- the type where I can have pay per click ads. Do I need to pay for a domain name? Can I have a free website and still have adsense on it? How do i do it?
