For people who are staying or working from home, this strange time presents an opportunity to start a new habit or finally read a productivity book like Getting Things Done. However, like any new project it can seem overwhelming at first. This can in turn lead to inertia and the old habits remaining in play.
Yet, it may not be as hard to change as it first seems. In a recent blog post, David Allen answered one of the most popular questions he receives about GTD: “Where do I start?”

I have a very strict and specific procedure that must be followed, without exception. If followed, it’s a guarantee of success. If not, well…good luck. Where, exactly, should you start? (Hang on, this is going to be tough…)
Anywhere.
Yes, anywhere. Any portion or component of the GTD approach, applied, will bring at least a bit more clarity, focus, and control for you—without exception. And very likely when any one thing is executed, it will create a reverberation effect and spread to other parts. It’s a holistic model—i.e., any piece can be worked, and it will add to the whole gestalt.

Read the rest of his advice on the Getting Things Done blog. As well, I recommend purchasing the new Getting Things Done workbook for a practical guide to implementing the GTD practice.
