How to determine for yourself the list of necessary knowledge/skills?

Question

IT education

Hello!
I will try to briefly explain the essence of the dilemma, perhaps someone has already encountered this, or it will be useful for someone to read for themselves. To begin with, I, by my (stupid or not) nature, are greedy for knowledge, but because of this, there is always suffering with the choice of one or another field of activity, because I want to know everything and everywhere .... stupid fear of missing something something important... I get interested in IT (probably because it's fashionable or/and because of money), then I dive back into something else, more familiar. I’ll explain with an example, I’m interested in consulting, and GameDev to some extent, there is also a craving for Data Science (not for monetary purposes), there is a corresponding list of knowledge for this, but is this enough? I mean, I get a feeling of anxiety and fear that I will miss something important ... some kind of Grail or something ... I understand that this feeling is stupid, I understand that a person will always learn new things almost every day all his life, but for me it becomes a very big moral problem to “calm down” and limit my knowledge needs ONLY to some specific things, some industry (for example, to the same 10 thousand hours are many known). If you have experienced or are facing something like this, how do you restrain yourself or do you need to restrain yourself at all in this case? I am very interested in things related to the process of logical thinking itself, analyzes, etc. But due to the abundance of everything interesting, I can’t put everything together into some kind of single system, I’m afraid to get lost in all this .... Already it seems that it would be easier to live without having a choice, or brains to think. I would be very grateful for all the feedback absolutely, from negative to positive!

We need to find a balance.
Example:
In order to get a job and adequately start as a beginner, you need to know a certain technology stack, be able to use software skills, know the computer science base, have analytical thinking, and a lot of time. Is it a lot? A lot
How the average programmer works: He went from junior to senior/architect. The level of his knowledge allows you to design complex systems, but ask him to write the syntax of a function, or ask for array methods - and he will go to Google, and that 's fine
don't have a genius, and don't move the whole sphere forward with new discoveries), your way:
1. Get a job.
2. Grow to a salary level where you don’t have to count pennies = the ability to save 20% of your salary for a financial cushion, + another 10-15 percent to invest somewhere + the opportunity to relax at least once a year + have middle-class property = a car , apartment, food.
3. Develop and expand your horizons by virtue of your profession (improvement of qualifications, or increase in skills for the sake of pleasure or salary).
Without having the first and second, to learn leftist technologies, just to broaden one's horizons, is idiocy and a waste of time. Better go in for sports, download soft skills, travel, live life to the fullest. Otherwise, all that you will take by the age of 50: poor eyesight, sciatica, hemorrhoids, and lack of friends.
Learn only what is included in the pool of only one technology, everything else is a forest, or after studying the first technology. Otherwise, you won't learn at all.

Answer 2

First, go through vacancies in areas of interest and write out what is often required and unfamiliar. Secondly, come to terms with the idea that it is impossible to know everything, and start prioritizing.
