GTD in just 80 words…
GTD is essentially about maintaining an exhaustive to-do list of actionable tasks in addition to a calendar that would hold only time-sensitive tasks, while you complete tasks that take less than two minutes, on the go. You would use the to-do list to extract the tasks for the coming week, every week, and then further extract tasks for the day, every day. You then visit the day-specific to-do list to pick up the tasks best suited for the time slots.
Conventional wisdom provides us with great principles, say, How to fill a jar with rocks, pebbles, and sand, or Time Management Matrix, but often we do not know how to implement these principles. These concepts are great and will remain valid forever, but without a system that implements them, the proverbial rubber never meets the road.
Of course, we can also find an endless number of practical tools, such as calendar apps, To-Do List Apps, and daily/monthly/yearly planners that indeed give us practical means for productivity. They are useful but do not solve productivity problems comprehensively. A calendar takes care of your meetings quite well. But what about the rest of your work?
But, to the delight of all of us, we have that fool-proof dream time/work management system, available by the name GTD (Getting Things Done). The reason it is foolproof is that it hits at the root cause of the stress at work. A careful reading of the book by the same name or guidance by a GTD coach can help you to implement the system. A good implementation of GTD helps to bring back the virtuous cycle of keeping up the promises made and feeling good about it and working better to keep up more of them.
