Actually, I think it's both: understanding AND an action based plan, or in other words, a cognitive-behavioral approach. My wife has struggled with this a great deal and has also improved significantly through both of these. With an understanding you can change your thinking patterns which can free up that need to procastinate; however, contrary to what that article says, time managment can be a big part, not necessarily the only, but a big help. I can't see throwing out either understanding or an action plan.

Thanks for the link, there's a lot of good stuff in it.
