if you're an idiot, i'd stick to moving back to "how to operate windows" if you're a genious, then learn php/mysql/actionscript/css/xml/ajax/ruby/jsp.
do what you feel is comfortable.. alot of the concepts that you learn in one will either apply to, or intertwine with other web technologies. if you feel that you're overwhelmed, then only focus on one language until you are comfortable.
