Table of Contents Let’s use packages Let's set the working directory Experiment with data types This time, the volume may be a little lower than the last time. Nevertheless, we recommend taking a break every 25 minutes. Why "every 25 minutes" is because there is my recommended concentration method called Pomodoro Technique.

Then, concentrate for 25 minutes again… You repeat this process to finish the tasks you are doing. If you're sayi...

Hi. Good morning / afternoon / evening. I’m ponpokorin ( @ponpokorin_24 ). In this article I would like to introduce Pomodoro technique first. This is one of the effective tools when you can’t concentrate. The name was given because the inventor used a timer in the form of a tomato (in Italian, tomato is "Pomodoro"). However, the specific method can be found by searching for "Pomodoro technique", so it is omitted here. So, what do I introduce? In Pomodoro Technique, you set the timer for 25 minutes and “concentrate”. In this place, how do you concentrate? It is a today’s topic. Being unable to concentrate on studying seems like a general problem. I think that there are people who listen to background music or favorite songs, prepare rewards, or use some other ways to study. I've tried many these methods, but I couldn't concentrate. That’s why I considered and wrote the following my methods, so if you already concentrate on studying in the ways list...
