CPA Etc.

Hey,

Basically I'm hearing about people earning $100+ a day.. i'm happy with $50 a day, how is this possible? Just a base to get started? How can I start CPA?

Sorry, im just new, i've searched around but not found much..

So basically my questions are:

1. Basically in a few words, what is CPA, and does it cost to start CPA?
2. How easy is it to get $50 a day?
3. Can anyone do it, and how much work is it a day?

Thanks SO Much to anyone who helps me!
