Things don't last because I'm not good at

If you don't like people or things, nothing will last.
The reason I never get tired of breathing air every day is because I “don't like it, but I don't hate it.”
Also, you can continue every day without being nervous, like “I'm good at breathing.”
Work, like breathing for you, lasts longer if you keep it down to a level that you don't like but don't like, and that you can continue every day.
Also, I think the trick to not disliking people at work is to not dislike their work and not even judge that person's work based on people's likes and dislikes.
It might be appropriate not to drag on anger or disgust, and treat them every day as if they were meeting someone for the first time.
The comic “Buddha and Sittakabutta” was interesting, although it's a bit old about Buddhist books.
Also, there are many books written by Elder Albomulle Sumanasara, a Sri Lankan monk (fluent in Japanese), and you can listen to them on audible.
After that, I think looking at this Hasunoha book and the contents of consultations from other questioners on Hasunoha will also be helpful for how to live.

I read it.
You're worried that everything won't continue, aren't you? I don't know the details about you or your surroundings, but it conveys what you're worried about. I understand your feelings from the bottom of my heart.
There aren't many things that humans can do for a very long time, and there aren't many things they are good at. It's a miraculous thing if you find it, and you may be blessed and find things that work well in the midst of various encounters.
Nonetheless, everyone is living now for the future. You are living well now, you are blessed with water and air, and you continue to live blessed with relationships with your family and loved ones.
Maybe being alive itself is something you are good at.
Please first be confident that you are alive now, and be grateful for the various encounters and blessings you have received.
Surely as you live, you will have even more reliable encounters and wonderful encounters waiting for you.
I sincerely pray that you will be blessed with many wonderful encounters and relationships in the future and that you will be able to live through the life you have been given together.
And I wholeheartedly support you.

I also read your past consultations.
They seem to regret quitting their club activities in the middle and high school years, and getting a job as a nursery teacher while getting a qualification at a junior college, but there's no need for that at all.
At the time, you probably thought about a lot of things and made a decision after worrying about it.
Life only moves forward.
Once you've made a decision, don't look back at the past.
It's talked about as if keeping things going for a long time is a virtue, and that too is on a case-by-case basis.
It's no different from wasting time in your life while just continuing lazily.
You probably still haven't found what you really want to do or what you really need to do.
You can continue to do your best to work on what is right in front of you, stop if you don't like it, and try the next one.
Move forward with confidence.
I want you to recommend a Buddhist book that will serve as a guide to how to live, so as I mentioned in other answers, I recommend “Dhammapada (Dharmapada).”
It is the most read Buddhist book in the world.
You could call it a textbook for life.
Various translations have been published, but I love reading “Buddha's Words of Truth: Words of Inspiration” (translated by Nakamura Gen, Iwanami Bunko).
I think that if people at home study Buddhism on their own, it's enough just to read this book over and over and continue zazen (meditation) as a habit.

I've been making my own decisions for a long time, so I think I can share with you any hints I can keep going.

What is the reason you're not continuing? Do you have any idea?
I don't think it's necessary to have big goals, but if they have meaning, it will lead to the ability to take action.

Before we take action on anything, we think about the purpose and value (meaning) of “why do we do it,” and then challenge things after being convinced. Then, the result is that once you notice it, it has continued.

I think there's a reason why I quit my job right away. It's not that you shouldn't quit, but quitting right away makes it hard to gain confidence.
If that is the case, at the time of job hunting, the conditions are narrowed down firmly, and preparations are proceeded while making assumptions about the future. Also, by having a lot of things you can make use of, the range of job hunting will expand.

If you are struggling with relationships with people involved, not limited to the job description, it is also important to divide that it is only a work-related relationship to some extent. Also, if you try to look at the goodness of people, you can see that partner has a wonderful influence on you. A smile makes a good impression on the other person, so if you always keep an eye on it, your relationships will also become smoother.
