Sometimes, it happens so that all the hardwork that you do gets wiped off in less than a second because of no fault of yours. Now, what will you do in such a case? Even if you do not have any kind of obligation to complete that task or target, the only option to do it is to start again from nothing. That is a lucky chance if you already have a saved draft somewhere else in whatever format or that you remember what you have written but if it is not so, like if you created each word on-the-spot as the words kept coming in your brain, it is almost impossible to recover those words, phrases and sentences because they were not well-settled or pre-rehearsed in structured way in your brain.
