Many of us, have read GM-sections in RPG, RPG blogs, forum discussions, and sometimes books about the storytelling art.
All of these contains tons of interesting tips/techniques (and some will contradict each other, you don’t GM a gritty mega-dungeon and high-school drama game the same way), so I am curious which ones are your favourite and how do you use them in your game
I think better advice in that situation is to find players who want to play the game you’re running. It might be fun to make a tunnel-exploration campaign, but I’m running that dungeon over there. We’ll do the tunnel thing another time.
Also, to rephrase your dad’s advice, know enough of the world to be able to add shit where you need to. I don’t even know if the world is round, but I don’t need to. If the players are in a church, I’ll make sure to know the popular religions in case I need to roleplay as a priest.
The players will find a way to make you need to.
No, the world is enormous and you only need to worry about a small part of it. There is literally nothing over there, and no reason you’d want to go there. The game is over here. Leaving this area is the same as leaving the game, which you are free to do.
Well… That doesn’t always go the way you’d want it to go.

As this “short” session shows.
You decide that if an when the players make it a priority with their choices.
They decide that with their choices. The only decision you, as a DM/GM have at that point is how to pretend that you had already covered that possibility.
