A useful tool that can help with time management is a planner or a to-do list. This allows you to prioritize tasks, set deadlines, and keep track of your progress. Other useful time management techniques include setting goals, breaking tasks into smaller and more manageable parts, and using time-blocking to allocate specific time slots for different activities. It is also important to avoid multitasking and focus on one task at a time. Additionally, practicing good self-discipline and avoiding time-wasting activities can be beneficial for improving time management.
