To use the Pareto Principle to improve your time management, you need to identify and prioritize the 20% of your tasks that generate 80% of your value. These are the tasks that align with your goals, expectations, and responsibilities as an administrative assistant, and those that require your skills, expertise, and creativity. Ask yourself what are the most important outcomes to deliver, the most urgent and critical tasks to complete, the tasks only you can do or do best, and those with the most positive impact on stakeholders. Once you have identified these 20% tasks, allocate enough time and resources to them. Utilize tools such as calendars, planners, or apps to schedule work and set deadlines. Techniques such as batching, blocking, or pomodoro can also help you focus on one task at a time and avoid distractions. To deal with the other 80% of your tasks, consider delegating them to other people or automating them if possible.
