You can always motivate yourself in distress and uneasy condition. We cannot work or meditate on our duty when we are overwhelmed by distractions. In this case we have to convince ourselves that we can think of all the stuff just after ten minutes. You can take aid of papers to write down your thoughts to remind those later after the work. And in these ten minutes we shall work on the one very thing we should. Thus we work by ten minute slots. And it works.
