We are, all of us, amazing at avoiding things. Our minds are less "thinking machines" than they are "avoiding machines". And the incredible thing is that we aren't even usually aware that we're avoiding thinking about something.
Procrastination is like a voice in your head giving you several seemingly valid reasons to avoid doing something. Usually it's tough to summon a counterargument to overcome it. So instead of shouting over that voice telling you to put something off until later, why not ask it a question?
If you're like me, you're always looking for the perfect productivity system. Unfortunately, it doesn't exist. The problem isn't with the productivity systems -- the problem is what no system can solve: Procrastination, the fear of uncertainty and the fear of discomfort.
