Carefully scheduling your daily program enables you to reach a better focus. As you plan your day, you should take care of dividing your tasks according to the available time. This way you will know from the beginning of the day what and when needs to be done, which will reduce considerably the time to make decisions, which is one of the main distractions when thinking to start a new task. Furthermore, including breaks in your schedule is almost essential, as these allow you to  recharge your batteries and, therefore, work more efficiently afterwards.

In order to improve your focus, you should actually try focusing on one task and one only. Therefore, make sure all possible distractions are being blocked, so you can devote yourself to only one task at a time. And, very important, make a habit out of it. Otherwise, it might not work in the long run.

When trying to reach your maximum focus, you might want to consider building up your environment in such a way that it triggers your brain to start focusing. Playing your favourite music, sitting in a certain spot or position, these are all factors that have an effect on your focus. Moreover, remember that tracking your hours can make a huge difference, as it enables you to see exactly how much time each task and distraction takes. Use this in your favour and you will become able to work more efficiently in less hours.
