trust me. don't think of it as starting hacking. Just start learning about computers, then hacking will just come naturally. Here's an analogy:

Say you're a lock maker. Since you make locks, it would be rather obvious to you on how to pick locks.

In the same way start learning about how the internet works. Learn various protocols. Learn how various operating system's work. Learn programming and how programs work.
