1. Shock yourself out of the inertia of the previous context by removing yourself from it quickly and decisively as soon as you realize it's time to get to work. Devote a few minutes to something as far removed as possible for the explicit purpose of clearing your head of what you've been doing. Do not delay. Leave things unfinished: if it is not as important as the task you're switching to, then by definition it can wait. 2. Start with the smallest, simplest, most self-evident and well-defined part of the larger task that you can think of. Reduce every task until you find something you can do right this minute without having to think more than a few minutes ahead, and repeat. Make reversible decisions by guesses or random selection if necessary to keep moving forward. Resist the urge to prematurely optimize by batching, list-making, or prioritizing until your attention is fully on the new task.
