You only need to choose what you really like and there won't be much of it, in fact. Films can be selected by themes and favorite actors who are filmed there.
For example, I primarily watch new comedy films, continuation of the franchises of films of interest to me, films about time travel and dystopia. Secondly, I watch films with my favorite actors, detective stories or thrillers. Usually I pass by dramas and films about crime. There must be a special reason for me to watch them, for example, an Oscar nomination. When I can't find novelties interesting to me, I watch films on similar topics, such a list is provided for almost every film on Kinopoisk. I also watch old films, I never limit myself to new ones, we have such a huge legacy of cinematography at our disposal.
With music, everything is also simple, I listen only to certain directions, I definitely do not keep track of new items in the field of rap or jazz. Sometimes I watch VKontakte music in the "Popular" section to be aware of what young people are listening to.
The only way out is humility, as the Buddhists taught. I comprehended the full depth of human depression when I realized that no matter how much I watched films, no matter how much I read, listened to music, etc., I could never know everything. This is a simple truth. Therefore, I just take and watch what I want at the moment and try not to remember how much of everything is left behind. I even started a special notebook to write down everything that I have to watch / listen / read and so on. The main thing is not to look at what is attributed to the necessary (in most cases, not always, of course). For example, everyone is talking about Game of Thrones, and it is definitely a masterpiece. But I watched only 3 seasons, I could no longer. And no matter how much they tell me that it is absolutely necessary to watch this series, I will not start watching it only because of this, because it is not good to watch it without much desire, as an obligation. Instead, I'll watch what I want (even if it's a gay anime). Everything has its time, as they say. Choose what you like at the moment and forget that there are a million more beautiful masterpieces somewhere else. You can't keep up with everything. Here, as with money, if you consume greedily and a lot, there is a chance that half will not be remembered, and another half will get confused, and some of it you will not be able to appreciate. And in general, it is worth saying thank you that we live now. It is hard to imagine how many interesting things a person can see in a hundred, two or three hundred years.
