For a real writer, finding an idea for a new article is as hard as finding an occasion to have a drink for an alcoholic.
But I have long periods of abstinence from writing, mostly when I feel that my writing is as – quoting my literature teacher – throwing the pearls in front of boars.
Kawandeep, you worry how to stipulate to write people who have nothing to say. In my book, they should be encouraged to read first. In particular, the writings of authors who have something to say.
For you, it would be best to worry why some authors who have something to say do not write as often as they would like to do.
