What in the world does sushi have to do with writing and publication? Nothing, and everything!
Have you ever watched a skilled sushi chief work? Have you ever watched how detailed his/her work is, how precise? You may also have noticed that his/her work also appears effortless.
Repetition breeds skill and ease. So too with writing. Remember, you are not supposed to be a master the first time you try something- it takes years of effort for something to feel effortless, and in truth, writing does not feel effortless to anyone all the time.
Now, if getting an article published was as satisfying as sea urchin with quail egg- life would be grand!
