My diary Today is a busy but happy day for me.I got at at 6.30 a.m. and then jogged around my neighborhood for around 40 min. I've kept the habit of doing exercises for one month and a half,which helps my stay in a peaceful state of mind and have a nice shape.However,with summer coming,it is a little hot and I dislike the sense of sweating since I feel sticky. I made a sandwich and a for myself as breakfast.It contained two pieces of toast,one fried egg,and tuna.I enjoyed it with a cup of coffee. The same as yesterday,I went to the library in my district after breakfast.I'm satisfied with my efficiency today,because of a time management app that I downloaded today!! It's called Forest,and it's actually based on Pomodoro Technique which derives from Japan.We can plant virtual trees on mobile phones and when the number of trees reaches certain level,we can even donate for tree planting in real life.This app is simple to use:We set a period (e.g.,15min,40min) during which we cannot touch our phones otherwise the tree will die,and when the period that we set past,we plant a tree successfully!
