What should I know before learning hacking?

Hey, I'm really interested in pen testing and want to learn, obviously I know you cant just "learn" and it takes a lot of time to build up skill and knowledge. But I was wondering what I should already know before I start to make the learning experience a bit easier, for example, should I fully learn how to use linux, what different network protocols mean, or maybe every port number and how they are used? Or should I learn all of this while learning to pen test? Any advice is appreciated, thanks!
