I am completely new to WoW...

Right, so I wanted to post in the "Getting Started" section, but it said it was for addons/installation tutorials etc. I wasn't sure if this was the right spot so yeah.
I am completely new to WoW (highest I got was to level 40 last year on official servers) and really didn't like the experience only because of how easy it was and felt literally no accomplishment to any level at all minus if I ended up getting level cap.
I just have a basic question, what are some tips or tricks all WoW players should know? Every online game has those "things" that all players should do (like in CS:GO to aim for the head then drag down for recoil), and I just wanted to know a few before I got started, thanks!
tl;dr: Gimme some newbie tips pl0x, like really newbie, like never even played WoW newbie.
