Serious answer: Scripts.
Well, two of the four types at least.
One type is the straight dramatic script where you front-load descriptions, use minimal details beyond that, and trust the actors and directors to come up with something at least as good as your vision. I am horrible at this.
Another type is the type of scripting for comic books and other visual media where you only have one other contact to worry about, the artist - have never really tried at this, but suspect it would be just as hard.
The third type is the "mini-script" or "adventure script" - a short (two pages at absolute maximum, usually a half page long) script to set the mood for an event, usually a role-playing game. After several years of practice, I got decent at this for some licensed properties (Star Wars, Doctor Who) but it is definitely not my strong suit.
The fourth type is program scripting which I am very mediocre at.
