I feel like my heart is too narrow

According to the Buddhist way of thinking, all life forms that occur as life are determined by karma. Since each business is different, humans are not born under the same conditions as individuals.
From the moment they are born, whose child they are, what kind of physique, what they like, what they dislike, what they are good at, etc., an individual must begin to live under conditions unique to that individual, and so on. In that sense, humans are not equal.
For example, even if a person who was born without arms likes music and wishes to live as a pianist, it will almost never come true. I can imagine a path where anything is possible in my head, such as developing a complete prosthetic limb that responds in real time or reconstructing both arms with revolutionary medical technology, but it is impossible to make it happen.
Even so, if you want to live without abandoning your intentions of “music” and “piano,” you may be able to choose a way of life where you go on to become a composer, become a typesetting performer using electronic sound sources, or make an effort to become a critic.
This is an extreme example, but the condition that Kiriha is an “older sister” and “has a younger brother” is basically the same. Even if you can imagine many things in your head, “if I had a sibling above me” or “if my uniform wasn't renewed,” that cannot be realized.
Humans live on a path that can be realized according to their own conditions. It is not a relationship of superiority or disadvantage or profit or loss between each other.
For example, even if an athlete in the 2000 meter race wins a gold medal on the same track where the 100 meter athlete won the silver medal, that does not disdain the silver medal of the 100 meter athlete. There's no such thing as which player is superior or which competition is winning; it's just that the conditions are different.
Humans suffer not because of the conditions they each have, but because they are trapped by their own imagination (delusions) that go beyond the scope and results that can be realized under those conditions.
In terms of Buddhism, the idea of “fairness” can be said to be a mindset where each life can help each other if possible without disturbing each other when living under different conditions.
Why don't you treat your younger brother with the mindset of “I achieved this kind of result under my conditions, you should aim for results under your conditions.”

I read it.
I feel like I can really understand your thoughts and your feelings for your younger brother. I understand your feelings from the bottom of my heart.
As you said, just looking at your past questions and imitating them won't improve your younger brother's studies. I think it's okay to tell them that clearly and watch the situation.
My younger brother is probably not going to take entrance exams, etc., so I think you'll know that he'll never pass just by easily imitating him. Conversely, if they are resentful, the bottom line is over, so I think it would be preferable to call attention and respond calmly.
Life isn't easy, and no matter how easy it is, you'll never succeed.
Please stay calm and keep watching.
You'll have your studies and career path, so please do your best.
I will support you from the bottom of my heart.

I get it~
I also had a hard time studying for which I obtained my qualifications, and when my husband used my textbooks to take the exam, I was confused.

I think you should lend me a book without saying anything stupid. it's all around.
But it's my trajectory of reading many books night after night, drawing lines to put them in my head, writing them out, putting them together... through hard work! It's filled with so much thought, isn't it?

It's not that you hate your brother, nor do you want to hold him back. I want to support them, and they are an important family. But that feeling and the feeling of being so unfortunate that what you've built is easily destroyed... it's complicated, isn't it?

However, even though we have come this far using the same text, my husband and I still have different attitudes and approaches to dealing with each other. After all, I am me. The experiences and abilities I learned and worked on back then have firmly supported me today.

Let's also cherish the frustration you feel about yourself, which you think is narrow-minded. That heart makes me want to do my best again! I don't want to lose! to myself! It turns into a guts like that, and it pushes my back. I want to support you too.

Thank you Kiriha 🍃 for your consultation.

Kiriha is a high school student.

My younger brother, who is in middle school, is studying for regular tests using past questions is confusing.

Somehow, having a straight older sister is a problem, isn't it?

I also had a younger brother, so I feel nostalgic.

The reason my younger brother doesn't seem to listen is that if I collect the same questions as my older sister, I might be able to go to a good school like my older sister!

There may also be a feeling like that.

I did my best to pass the school on my own, but on top of that, I felt like I was being handed over by a ladder, and somehow I was confused.

All of this means you can't choose between being born as an older sister or younger brother.

But Kiriha's hard work is definitely not going away, and it's piling up in my life!

I'm still in high school. It's natural for people to be narrow-minded.

Rather, it's too straightforward and clean!

Even after becoming a member of society, please make full use of that sensibility and dislike of losing, and definitely play an active role in various ways.

I'm looking forward to it now ^_^

By the time Kiriha became a member of society and her own world was established,

There are times when you miss your current feelings.

Oh, there was a time when my little brother felt that way.

If possible, I would like to honestly support my younger brother in his studies. That's because Tomo already said it himself.

From now on, it might be nice if I could show my younger brother more and more of his back and use him as an example.

I'm sure you'll be able to become a wonderful older sister, no more and more!

I'm rooting for you ^_^
