Adsense Vs ClickBank Vs CPA : which one is faster

Hi, all.
I'm a complete newbie. I can almost hear someone cringing "oh, no. one of those posts". Per my nativity and optimism, I'm starting my affiliate marketing journey. Unfortunately, I don't have much experience in adsense, clickbank or CPA marketing. (studied but no experience) So if you can give me some guidance on which one is better, I'll go on my merry way to be a great affiliate marketer.

Of course, I recognize that these 3 examples are not direct substitutes for each other. all of them have their strengths and weaknesses. It also will depends on my budget, skill, time and study. (don't worry. I lack all of those things. ) Any and all insights, tips or experiences you can share will be very appreciated.

I don't stand to make multiple sites. And looking for something that's going to make me the most amount of total income in the next 60 days. At this point, ad-sense seems to be the weakest candidate. I could be wrong, of course. I do have my own blog(not doing well, not created for income), but willing start a new website if it comes to it. I don't know how much I can realistically make in 60days, so I'll be grateful for any thoughts you have on that as well.

I thank all of you for your time, knowledge and generosity in advance.
school is in, and I'm ready to learn.
