Use the Pomodoro technique for literally any work... 30 minutes work then 5 min rest... It is one of the best technique to improve concentration and be productive

Write tasks on paper....then try to divide them into small parts...for example- If I have to do a work of 60 minutes then try to break it into 2 parts 30 - 30 minutes each....between them take a 5-minute break...So overall your 60-minute task was completed in 65 minutes.... 👍🏻
