My favorite mistaken belief is that my task will take less of my time in the end if I procrastinate. For example, if I think I will spend two days on the task if I do it early then I will worry about missing my whole weekend. My favorite mistaken belief is that if I procrastinate, the same task will only take two hours of my life.
I discovered an idea for success this week and it worked for me one time this week. I did the task early but I limited myself to a certain time period to work on the task, the same amount of time that I imagine the task would take if I procrastinate. In the end my task was not perfect, but I was in an improved position by doing it early instead of procrastinating. I also did not spend the whole weekend on the task.
