Humans are not interested in anything to begin with. What they find interesting is up to them.
No one is born with an interest given to them. There's no such thing as being born and thinking, 'I'm interested in this.' Therefore, people's interests and goals are ultimately formed from experience. If you live a life where you can't decide what to focus your interest on, then your interest won't be directed anywhere.
So, it's perfectly normal for people who are worried about not having anything to devote themselves to, or not knowing what they want to do. There's no need to belittle yourself just because you haven't found it.
There are roughly three types of ways people's interests are directed, depending on their personality.
Rather, many people who decide 'I'm going to do this!' midway through life often have an inferiority complex. If you fall into a single-minded focus, like 'I'm bad at this, I'm bad at that, but I'm good at only this!', you can achieve results early on. After that, you gain successful experiences, and it becomes set as 'what you should do in life.' However, as you grow older and learn how to use your mind, you might realize that you can try and succeed at anything else, and even the interest originally gained through single-minded focus might shift to other things. Succeeding at one thing means you can succeed at others by applying the same thinking and mindset.
Or, there's the type who is good at many things, but exceptionally good at one! This is the 'Superman' type who learns how to use their mind early on, succeeds at everything they try, and also finds something they want to master. I feel that these kinds of people, unlike those with an inferiority complex, tend to have high pride. Everyone aspires to be like them, but parents often don't know how to teach 'how to use your mind,' so such individuals don't grow up easily. Furthermore, if they succeed at one thing, they can apply it and succeed in other genres as well.
And the most common type is the 'average' type in the middle. Average in sports and studies, and reasonably good at social interactions. People raised in this position find it especially difficult to discover what they truly like. Unless there's a shocking encounter that makes them think, 'I want to do this from the bottom of my heart!', most people just have to proceed with 'maybe this is it.' With 'maybe this is it,' for example, they go to university or vocational school, or get a job and enter some industry. If they continue there for a long time, results will come, and eventually, their own field will be established. However, this is just about establishing their field, and I think many people would question if it's truly what they should be doing in life.
Most people in the world are the 'average' type.
Most people in the world are the 'average' type in the middle. Furthermore, even if they are another type, it's rare for their interest to remain focused on just one thing. So, I think many people live by making something they've spent a long time on their job, thinking 'this is it,' while suppressing thoughts like, 'Is this really what I should be doing? Isn't there a way of life I truly want to achieve, rather than just what I 'should' do?' It's good to ask your heart: 'Is my current job truly what I should be doing?'
But even if you ask, 'What do I want to do?' won't necessarily come up. I think that's normal. Even if something temporarily emerges, when you achieve it, will the next things you want to do or devote yourself to keep appearing one after another? To seek something means to achieve it. That might happen surprisingly quickly, or for some, it might be unattainable. But usually, if you're serious, you can achieve anything.
After achievement, which is the destination for everyone. This is the crucial moment. Can you find the next things you want to do, one after another? If you can't find motivation for the next thing you want to do, you'll just wander. No matter how much you want to do something or achieve a certain state, it will eventually be accomplished. That's why I think it's necessary to consider motivation after achievement.
The ability to sustain motivation in a loop of achieving and finding the next thing.
Humans are not born with things they inherently want to do. Therefore, it's necessary to have the ability to enjoy the loop of creating walls to overcome one after another and figuring out how to surmount the walls you've built yourself. You set your own goals and push forward towards them. This is often the most enjoyable time. And once you achieve one, you create the next wall and achieve it. You need to cultivate yourself to be able to find pleasure in this repetition. Perhaps that is true spiritual talent and something to master.
There's a concept called logical thinking. Logical reasoning, and so on. If that is a 'practical science' for achieving something, then the trait of finding pleasure in the loop of creating and overcoming walls might also be a 'spiritual theory' for achieving spiritual success, I sometimes think.
I myself am far too immature in this spiritual theory. Even when I try to create the next wall, my motivation doesn't rise. If I just abandon myself and create a wall and try, it becomes fun as I do it. But getting to that point takes quite a while. I might need to delve much deeper into how to fully open up my interests one after another and then overcome the next wall.
