Quick intro to MLO and GTD
One of the things that was different about GTD when it came out was it advocated a bottom up approach to task management which didn't begin with trying to create a grand plan. The first job is to completely empty your mind and all of your digital and paper systems of "To Dos" into ONE trusted system. In this case your trusted system will be MLO. At this stage, the really important thing is to put EVERYTHING in this list. Don't worry about whether it's a project or a task, whether it will happen or not, whether it's high or low priority, what you need to get it done, how long it will take, whether it's urgent or not - just create one long list. Having done this you'll feel a lot better; you'll be a bit daunted, but you'll be ready for the next stage which is organizing the list. The point of the Outline is to group related tasks together and then create sub-tasks which eventually reduce tasks, however large, into something which can be done quickly and easily. You will end up with a lot of tasks but the To-Do view in MLO will apply filters to allow you to focus on, amongst other factors, what can be done now, and in what order. You can forget about the bigger picture and just concentrate on doing stuff. There's much more but if you can do all this it will be a good start.
One of my favourite resources for understanding GTD is still the talks between the creator, David Allen and the productivity guru, Merlin Mann. They were recorded in 2006 but remain insightful about what's involved in getting organized and getting things done. You can catch them
here. It would probably help to have a general understanding of GTD before listening but it's not essential.
