Having a clear idea of ​​what needs to be done and when can help you stay on top of your work. Make sure your goals follow the "SMART" rule (i.e. they are specific, measurable, achievable, relevant and time-bound). This will help you break them down into smaller and manageable chunks that you can complete seamlessly. A pragmatic strategy is also to establish a permanent routine and stick to it as best as you can. This essentially means setting specific times and days when you will complete certain tasks - while scheduling breaks at regular intervals. In the meantime, if you notice your concentration slipping, you can do some simple mental exercises or take a short walk to clear your head.
