Whenever you feel your attention begin to wander, stop and tell yourself to “be here now.” You may have to do this several times, but you will be gently reminding yourself that you want to focus on the task at hand. If you do this consistently, you should find that you gradually spend less and less time being distracted.

Turn off your phone if you are able, or at least keep it on silent and away. If you can't stop this distraction, look into apps or browser plugins that can block social media,...

How would you rephrase that briefly using Vietnamese?
Giữ tập trung bằng phương pháp “ở đây, ngay bây giờ”. Gạt bỏ các những thứ gây xao lãng đặc thù khi bạn nhận ra chúng. Cho bản thân thời gian tạm nghỉ để lo lắng. Ưu tiên cho việc học bằng cách đặt ra mục tiêu chính. Thoát khỏi mạng. Lưu ý đến mức năng lượng của bạn. Thỉnh thoảng nghỉ giải lao. Đừng cố làm nhiều việc một lúc.
