Recently ,I have read a book about Pomodoro Technique written by Francesco Cirillo.The book introduces a new way of managing your time when you are studying or woking.Firstly ,you should list what you planed to do in the day and set your timer for 25 minutes,then you start the first task without stopping until the timer rings and you can have a rest for about 3 or 5 minutes.The break time goes by ,you go on with your task and cycle all the time till the task is finished and remove the task from the list.You could have a long-time rest for 25 minutes after you finish every 4 tomatoes.I am interested in this way and want to have a try.Have you heard of this or had a try?What do you think of it?
