I want to see the world, help?

[AceofSpades]

I graduate in december and before I start grad school I'm thinking of buying a plane ticket to europe and traveling around italy, greece, spain, morocco and supporting myself playing poker by playing on a laptop in coffee shops/wifi places.

I need a general idea of how much I need to make to cover living, travel, siteseeing expenses per day. Can anyone give me a rough estimate what I need to be making and any tips? I don't really know anything about passportes etc. I don't mind staying in cheap hostels, but I'd definitely want to have enough to do cool stuff and go out, etc.

how do I get started?
