I have recently become very interested in Pen Testing/Ethical Hacking.  So much so that I already have numerous books, slides, course studies, training boot camp videos....and so on.  The more I learn the more I want to do this. I have basically decided that this is what I want to do.  Period.  I have never really worked for a IT company nor do I have a Single Cert. or a job that is involved with security/IT. Where do I start? Specific Please! What is the very first step.  I have be to countless websites and I still feel like I dont know how to begin.  Any advice would be appr.

Thanks
