5 Tips to improve your focus
It can be pretty challenging to focus on a single task if your mind is constantly wandering. If you're tired, exhausted or overworked, it can seem almost impossible to concentrate on anything.
However, I listed five tips that can help you increase your focus.

Eliminate distractions: A simple way to improve your focus is to eliminate as many distractions as possible. Many people distract themselves without even realizing it. The first step toward improving your focus is to identify areas that distract you. For example, if you constantly find yourself drawn into online social networks like Facebook, it may be time to take a social media break.
Stop Multitasking: Give your full attention to one thing at a time instead of trying to multitask.
Be present: Live in the moment and pay full attention to what you're doing. If you find yourself thinking about things that happened earlier in the day, or worrying about something that might happen tomorrow, try to focus your thoughts on what you're doing in the present moment.
Practice mindfulness: When you're practising mindful breathing, for example, focus your awareness on the sensation of breathing—the feeling of your breath coming in and out of your nostrils, the movements in your chest and stomach as you breathe, etc. Whenever your mind wanders to other thoughts, gently redirect it back to focusing on your breathing.
Pomodoro Technique: Give yourself a break every hour or two if you're trying to concentrate for a long period of time. Many people find it easier to focus if they work in short, intense periods and take more frequent breaks. This is called the Pomodoro Technique.
