I think the answer to this problem is not any productivity trick, but to aim for exponential growth of your business, career, etc. so that Delegate becomes the primary workhorse instead of Next Actions. Prioritize actions you perform and projects you start so that they are conducive to a long term self-sustaining increase in your productivity. And accept that you may have limited success/luck in unleashing the exponential and that some projects will forever stay out of your linear reach.
