1. Plan ahead.
Start your day with planning. In the evening of the previous day or in the morning, make a list of things that need to be done. This will help you better understand the amount of work and prioritize tasks.

2. Set priorities
Not all tasks are equally important. Use the Eisenhower Box method to divide tasks into four categories: urgent and important, important but not urgent, urgent but not important, and not urgent and not important. This will help you focus on really meaningful things.

3. Use time management
Time management techniques like Pomodoro can significantly increase your productivity. Work for 25 minutes, then take a 5-minute break. After four such cycles, take a longer break. This will help you stay focused and avoid burnout.

4. Avoid multitasking
Multitasking may seem effective, but it actually reduces productivity. Focus on one task at a time, and you'll see how you can get things done faster and better.

5. Delegate tasks
If you have the opportunity to delegate some tasks, feel free to use it. This will free up your time for more important things and help you focus on what really requires your attention.

6. Set realistic goals
Don't overload yourself. Set realistic goals for the day and don't try to do more than you can actually accomplish. This will help to avoid stress and frustration.

7. Use technology
There are many applications and tools for managing time and tasks, such as Trello, Asana, Todoist, and others. Find the one that works best for you and use it to organize your day.

8. Don't forget to rest.
Rest is an important part of a productive day. Make sure you have time for breaks and rest. This will help you maintain your energy and motivation throughout the day.

9. Analyze your day
At the end of the day, analyze what you've managed to do and what you haven't. Think about why some tasks have been left unfulfilled, and how you can improve your productivity tomorrow.

10. Be flexible
Life is unpredictable, and sometimes plans can change. Be prepared to adapt to the changes and don't get upset if something doesn't go the way you planned.

By following these tips, you will be able to better manage your time and keep up with everything you have planned for the day. Remember that productivity is a skill that can be developed, and you will get better and better every day!
