I once read from a book that an author meets with difficulties such as the barrier of thoughts and flow of ideas. When that happens, an author should not leave his/her work because if they do, they wouldn't feel like getting back to it anymore and will be inclined to stop writing that story. Its only when they're really determined to overcome and complete that particular section then will they continue writing the rest of the story.
I'm facing this kinda situation now. I'm stuck. I don't know how to continue with the report. But at the end of the day, I would still have to complete it. I should stop whining about it and CONTINUE DOING IT.
