This is fine for an experienced player, perhaps even someone returning from Wrath, or transferring from FFXIV. They know the MMORPG ropes, and can make their own decisions.
This is terrible, terrible advice - the worst possible - for a new player.
New players need time to mess about, experiment, chase things, enjoy.
I’m currently keeping an eye on a newcomer who recently hit 120.
Ma-an, trying to explain the basic endgame systems to a new player is HARD. They make no sense, unless you have been learning them for years. (Even then, most of them don’t make a lot of sense if you think hard about them.) As I explain them, I keep thinking to myself “Who thought that was a good idea?”
Anyhow, he’s just dinged, and he was asking what was his next step. So I explained open up World Quests, and I checked his armoury, and he needed some rep with Zandalari and Voldunai, and a third foothold.
Now, if that was you or me, we’d be like “How much rep?” “What’s the fastest way to get it?”, and laser focused on the goal.
Not him. 
He banged around and eventually did his third foothold, though he mixd up Drustvar with Darkshore in the process, not figuring out how to get to, and from, the places he needed to be.
I thought he said he had done Zandalari. I’m pretty sure he did say that, but he must have misunderstood something, and found his way to start Vol’dun, where he mentioned the going was slow. So I logged in to bodyguard him for a while.
And I watched. Here is some footage I recorded:
OK, so that is not actual footage. But it’s close. He was running everywhere, bodypulling everything, going into every nook and cranny, and just generally having a great time.
Remember, this is the same guy who said he wanted to get to some gear ASAP.
So he hit Friendly in Vol’dun and I said time to fly down to Zuldazar to polish off that bit, so he could get into world quests and warfronts and like that. Didn’t want to. Just kept following quests, killing stuff, would have died several times if I didn’t step in, and generally enjoying himself.
Let new players have their WoW childhood. They’ll be strapped in to the inflexible artificial constricting endgame systems soon enough!
