Do you happen to know Writer’s Block? It is a condition where an author cannot start a new work because of the fear that he might not create a great one. The best way to break down this barrier is to start writing a sentence.
When you put off things that you want to do or that you have to do, you say it’s hardly even thinkable. To speak more precisely, it’s not that you’re unable to start because it’s hardly thinkable, but it’s more like you don’t get motivated because you haven’t started yet. According to Work Excitement Theory reported by Emil Kraepelin, a psychiatrist, once you start doing something, a certain part of the brain become excited and enables your body to keep doing it. For example, though you have no appetite, if you begin to eat, your appetite improves; though you are forced to start cleaning a room, later you come to clean every corner of the house.
If you are hesitating to do something, just start it now. Then, it’ll wake up the body and help you focus on it.
