One of the fundamental aspects of time management is task prioritization. Entrepreneurs can use the Eisenhower Matrix to categorize tasks based on urgency and importance. Tasks that are both urgent and important should be tackled first, while those that are neither can be delegated or postponed. Another effective method is the Pareto Principle, which states that 80% of results come from 20% of efforts. Identifying and focusing on these critical tasks can significantly enhance productivity.
