"The key is not to prioritize what's on your schedule, but to schedule your priorities." - Stephen Covey

For a fast-paced environment, adopt the "Time Blocking" technique for your tasks. Instead of a general to-do list, allocate specific, non-negotiable blocks of time in your calendar for each priority. Treat these blocks like important meetings. This forces you to be realistic about what you can accomplish and helps you mentally prepare for focused work, reducing context switching and the feeling of being constantly reactive to urgent requests.
