A compelling explaination for the why of procrastination:
The particular nature of our aversion depends on the given task or situation. It may be due to something inherently unpleasant about the task itself — having to clean a dirty bathroom or organizing a long, boring spreadsheet for your boss. But it might also result from deeper feelings related to the task, such as self-doubt, low self-esteem, anxiety or insecurity. Staring at a blank document, you might be thinking, I’m not smart enough to write this. Even if I am, what will people think of it? Writing is so hard. What if I do a bad job?
