I can't really help you with the whole finding Haruhi Suzumiya thing. I can offer some thoughts on something else that seems to be more at the root of what you are looking for.
To me it seems that you seem to think that normality and boredom are necessarily related, which I don't think is the case.
Concerning normality, of course normality exists. I cannot understand how people can claim it doesn't. Being normal simply means that something conforms to a norm, as the term already suggests. What form that norm takes depends on what question you ask or what claim you make. One obvious example that normality exists is clothing. Glove manufacturers don't sit around not knowing how many fingers their gloves should have. It's five. People normally have five fingers per hand. There are people with more or less than five fingers, but that doesn't matter for what is normal. That something is normally the case does not mean it is always or necessarily the case.
When it comes to lifestyles, which you seem to be getting at, then of course normality exists. If the number of entities in a distribution is large enough it tends to become a normal distribution. The question here is how abstract or generic your claim is. I can say that everyone on this forum will have a normal life if by that I mean that they were born, live and then will die. Maybe there were some miracle individuals who did not have that kind of life, but again, it doesn't matter because the claim is about what is normally the case not always or necessarily the case.
If you take less abstracted or less generic claims, even then normality exists in lifestyles. Like you have said, normally people wake up in the morning, normally people drive to work, normally that drive will fall somewhere between ten minutes and two hours, normally they go home after work and so on. Again, this does not mean that this is always or necessarily the case, but to say it is not normal is simply empirically false, and can be refuted quite easily. Claims about normality cannot be too specific, since then you would not have a distribution that can be normal. If your drive to work takes between ten minutes and two hours you are probably normal in that sense. Not all or most people might take exactly 43 minutes to drive to work like you do, but that doesn't matter, because 43 minutes is still in the margin of normality in that distribution.
However, just because things or your life is normal in many ways, does not mean it has to be boring. Study on boredom has actually increased significantly in the last few decades, both in psychology as well as in philosophy, so there is a lot of literature there. According to studies in indigenous populations being bored seems to be an innate human experience, not just some modern millennial phenomenon as some might suggest. As with many things, boredom normally will be a function of both your own personality as well as the world around you, which can be shown empirically quite well.
More concretely in your case, it seems that you seem to think that knowing about something or having experienced something makes it boring, which I disagree with a lot. The more you know, the more you will realize how much you actually don't know. Like @efaardvark has pointed out quite well, people sometimes simply have a false view of things. I think many people who have not done a lot of fundamental science or philosophy tend to think that we have figured out most things. If you look at something we think is well known, you will see that things are a lot more vague than they seemed. If you disagree, try and think of a single thing, whether that is something empirical or conceptual, about those fundamentals you have mentioned and see how much you actually know about it.
Additionally much of what you describe seems to go after some 'sensational' way to get excitement, meaning something that you experience through your senses. Like others have said, concerning sensational excitement, the world today has more to offer than at any previous point (again to show that boredom is partly a function of the world around you). This reminds me of people who were not able to hear and then hear for the first time which is really exciting for them. After a while they get used to it and it is not exciting anymore. But I think that is just because people don't pay enough attention. I assume that is one of the reasons why so many practices from eastern religions are being misappropriated nowadays to improve western lifestyles. I think there is a lot you can do concerning yourself if you find yourself being bored all the time. This means that another person can certainly help there but it will have to do with yourself as well. Whether you find something to be exciting or a mystery will also depend on your own mindset.
