Francesco Cirillo has a timer which shaped like tomato and tomato called pomodoro in Itallian this technique was developed in early 1980s .
Basically this technique method is you have to assign a task to yourself. Then you set a timer for 25 minutes. After 25 minutes, you have to take a break of 5 minutes .
Then you repeat this process 4 times. After your 4th turn, you have to take a break of 15–20 minutes. After that break complete your task .
