Is there a limit to google adsense on sites?

Tweet

What i'm asking here is, is there a limit to the number of sites you can have with google adsense, or can you go on and on forever as long as you don't break the rules? I wanted numerous blogs that talk about different things from financial advice, to music, to even videogames. I was also planning on making a website or two & if there is no limit to the amount of websites one person can use with google adsense, I would definitely save a lot of money! I think I brought up a discussion like this before, but i'm not 100% on that, and well.. dialup doesn't really give me much room to search for it.. considering it's extreme slowness! =( So uh, feel free to help me out here and clear this up for me! =)
