Give up the idea. "Hacking" is not as easy as movies make it seem nor is it something you can learn how to do over night or even months for that matter.
If you're serious... Start by learning a programming language such as c or c++ also learn system architecture, memory, networking, reverse engineering, hardware, cryptography, etc.
Without this broad knowledge I would not even attempt or think you'll be able to "hack" anything.
