There are tasks that really do need to be done. No magical fairy is going to come along and do your taxes for you or some household task that someone really does need to do.
On the other hand, there are projects that aren't time-critical and that, if you hold off doing them, the need for them may really go away or you may otherwise decide that task isn't actually necessary.
And of course, there are always at least two possible paths there -- you can try to change it, or you can decide that you're actually okay with your life-under-procrastination after all.
But sometimes some people are going to find their severe procrasnation is interfering with their ability to do what is important to them, and they want to do something about it. This decision alone does not make it _easy_ though. My observation and experience have matched the articles, that self-blame doesn't help, but that recognizing the relation it has to your anxiety and finding other ways to relate to your anxiety can.
