...You people write?! That's surprising.
Hmm... creating an outline is the most logical start when creating a story. Nevertheless, there are some that create their outline after writing the story and then implementing some fixes on it. For beginners, they tend to write stories before their outline - and in which most cases, reasons why their story has a lot of plotholes and mistakes. Also, instead of publishing it on the internet, it's best to make it unlisted so you can read it anytime and point out mistakes yourself rather than having someone on the internet find it for you and mock you for your mistake. (Basically, learning the hard way without depending on someone outside... you know, think outside the box.

)
If anyone out there has created something beautiful without having to start with an outline - then be proud! That's many ways that writing a story is for you - and you're improving vastly.
Multi-tasking for writing is an efficient way to use time but difficult to handle against those who are stressed, have a lot of complications, and don't know how to write solidly (you can't write a shit story as you multi-task). Also, you can't do multitasking if your hand is on one keyboard because writing two different things at the same time doesn't work. Thus, it is not multi-tasking, but wasting time on trying hard.
Anyhow, shouldn't people be learning English before generally publishing their own work? I mean, writing isn't a one-way path to discovering tricks and techniques in improving writing. You probably know this, but making an outline can be learned at a very early age in your English session! Logically speaking, different information to become better at writing is left in school for you to listen to.
That's all... now oke doke, good game well played - go do your leg day!
