About me:
I was sick when I did all this security stuff.
My advice: forget about computers hacking and nerd stuff. Enjoy life. Life isn't inside a screen.

Be healthy, strong, intelligent, and sensible. And don't be a psychopath.

Life is good and everything will be alright.
Oh and don't forget to visit Portugal.
