Thy name is procrastination

I have 5 major, urgent, must-do things to complete this week. They were all due last week or earlier. One includes paying a rather important bill. Hi, I'm a procrastinator.
It's been my weakest link since childhood, the ability to push the limits of my deadlines and pay by dates. Is it a vice? Or is there some latent underlying problem that creates this endless lateness? I hate it, I know it, I can do something about it, but it's there.
I even procrastinate writing in this blog, but at least it's not an urgent matter. The bills however, are another matter altogether.
