I want to quit my part-time job

You've been able to work hard so far in the new environment of entering a university. My mind and time have been taken away, and I can see how they are suffering.

In conclusion, if possible, it is a good idea to move forward in the direction of quitting that part-time job.

In Buddhism, there is a word for “abandonment (bounce).” It means letting go of excessive obsessions. I painfully understand the feeling of being “uncomfortable with the people in the school building,” but it is nothing but an obsession with the convenience of others. You don't have to worry about it at the cost of your precious student life. Gather up your courage, let go of your obsession, and flatly refuse an empty shift “to concentrate on your studies.”

Anything that interferes with “schoolwork,” which is a student's original path, should be avoided as much as possible. It is said that there is anxiety about income, but starting from summer vacation means that life was possible even without a part-time job at the beginning of enrollment. The first thing to do is “know enough.” Let's review companionship expenses, etc., and first devise ways to minimize expenses.

Even so, only when it is extremely difficult to maintain tuition fees and living expenses, one way is to consider scholarships from the Japan Student Services Organization. However, since you will be obligated to repay yourself in the future, it is wise not to use it if you don't need it, and keep it to the minimum necessary when borrowing.

Time is life itself. Please value your own heart and learning path the most.

Thank you for your question.
Since you're a university student, it's a good idea to give top priority to classes and study, and then use the days and hours you can spare for part-time work. Also, rather than having different days and hours every week, I think it's easier to set up a schedule if the days and hours are fixed. On top of that, I think it's a good idea to choose a part-time job that suits you. If you do that, I think it's easier to make time with friends and family.
So I think it's a good idea to fix and specify the day of the week and time for the cram school shift. That's because your schedule won't be decided if it's decided due to the circumstances of the cram school.
If the day of the week and time you can dedicate to your part-time job really doesn't suit you, as your father said, you should look for another suitable part-time job.
Also, thinking about things that require preparation for a part-time job, or thinking about part-time work when outside of part-time work is common in other part-time jobs, and they also get used to it as my mother says, so I don't think it's too much of a problem.
I think the biggest problem with part-time jobs at cram schools is that students' grades don't improve. But if I'm going to take the exam myself, I should do my best in my studies, but getting students to work hard doesn't go the way I want. That's where I do what I need to do as a teacher, but I think it's also necessary to decide whether or not to learn it over and over again, and it's up to the student to decide whether or not to learn it. Also, I think it's more important to teach the fun and methods of studying than simply teaching how to study.
Also, if you feel pressured to be blamed by other teachers at the cram school, you might feel more comfortable being a private tutor. However, if you are a private tutor, you have to go home, so it may take some time to go if you are far from your home.
Also, since part-time work is not only an income, but also a social study, it's fun to try various part-time jobs. Of course, there are times when I make mistakes and get scolded and it's painful, but that is also social studies. Maybe my father wants me to have a lot of experiences.
For now, please give top priority to classes and enjoy your part-time job too. Let's say no to the shift we want to refuse once and for all. It's also my job to say no properly. It's important not only to refuse a part-time job, but also to refuse anything you want to refuse even if you get a job in the future.
Please enjoy your college life.

By the way, are you okay with your studies?
I want to think about each student and prepare and hope to teach because I am sincerely facing my work. Taking responsibility as a professional is probably basic.

Also, in specialized jobs, preparations are made outside of working hours, so that time is also taken. If you want the experience you can get from this part-time job, there's a point in continuing. If you think it's a burden, ask for a shift change as soon as possible.

Your income will decrease, but it's about reviewing your lifestyle and making ends meet. If you get your studies, income, job description, and fulfillment, don't be greedy, and evaluate them by priority.
Both parents are right on their advice. The choices will be different depending on what you prioritize.

Let's make a decision by worrying carefully. Once you've made up your mind, make your own choices and be convinced that this is fine. You won't have any regrets that way.

I read it.
I see, I read that you are worried about your part-time job. I feel like I understand very well that you are bothered like that. I understand your feelings from the bottom of my heart.

As you said, I don't think it will be a solid job if you don't prepare even outside of part-time work time. You're probably familiar with it, but I think they've taught you that making money isn't easy.

Nonetheless, I think exchanges and activities other than part-time work are even more important for you. It is very important to carefully measure and examine that point. Thinking, examining, and making your own decisions is a very important process. This will lead to your growth.

There may be other high-paying part-time jobs, but there are risks, and it's not that easy to earn money. Undercover work is the riskiest thing, because it's a crime. Please be careful not to be fooled by such dark part-time jobs, etc.

I sincerely pray that you will continue to experience various encounters and events and grow healthily as a person, and that you will be blessed with many relationships and live a truly rich and fulfilling life from the bottom of your heart.

I understand very well what you are saying.

When I was a student, I also worked part-time as a cram school lecturer, thinking, “I wonder if I can do a job teaching people when students are divided,” but on the other hand, “that's why I should try it out.”

Once you try it, preparation is difficult, isn't it?

Assuming what kind of questions would come from the students, it took about the same time, and sometimes twice as long to prepare for 1 frame.

And then there's scoring.

It's easy if it's just ○× and points, but the more serious you look at it,

“Why did I make a mistake?”
“How do I explain it to understand”

There is no end to it.

Therefore, there may be an aspect where “once you get used to it, you can do it without preparation,” but if you feel “I don't like teaching without preparation,” I think that is rather honesty.

However, when the university life itself is pressured because of that honesty, it turns the real deal.

University life includes studying, time with friends, and time with family.

I don't think you have to choose between quitting suddenly and continuing.

Only regular students are in charge, and other substitutions or additional shifts are not permitted.

Wouldn't that be fine for a start?

If it's not time for class yet,

“I want to balance my university life and review my available working hours.”

You should tell them as soon as possible.

Even if it's a little awkward,

It's more important to protect your time and heart than to be awkward.

Incidentally, I got fired right after thinking about quitting or not quitting (laughs).

After that, I switched to a part-time job with manual labor, but once the work was over, I really finished my work.

That feeling of liberation was exhilarating.

A part-time job is also an experience.

Trying it out and finding out “it's not for me” is also a great harvest.

First, I'll narrow down my work.

Even so, if the burden is too high, I will quit.

That's enough.
