How to overcome NIH syndrome?

Question

Career in IT

Hello. NIH syndrome - rejection of someone else's code.
I am a full stack developer. Every time I switch to the frontend, I get really sick of the node_modules folder. It's bad, because I don't understand how and what works there. I am offended not because I have not written this now, but because I have never written such a thing in principle. Using a library that does not understand how it works, I feel weak and humiliated or something ... How can you create something valuable and great (yes, yes, I like to set high goals, even if it seems to you that this is nonsense), if you don't know how to write the same Vue, Webpack, how does it all work? I don't want to be a guest worker programmer and freelance websites. I want to create something more serious ...
Here I am writing and I understand that I am missing some serious project of my own. Because of which I can use everything else with peace of mind and tell myself, but I am a narrow specialist in this :)
How do you deal with NIH syndrome? Did you have it?
PS Please, huge, no need to hate. Programming for me is not just a job, it's a hobby, passion, the ability to create something...

Answer 1

I am a full stack developer.

Are you sure that you are a full stack developer after such statements?
If you don’t understand how something works, either you score it, or you take it and figure it out. Yes, long. Yes, it's difficult. And make a shield.

Answer 2

When you were a small child, then for you the letters seemed to be unknown squiggles, and writing each letter required a lot of work, but they still didn’t look much alike.
Now you can read and write. You have learned it. So it is with programming.

Answer 3

You misunderstand NIH syndrome. This is not a psychological state of the individual, this is the practice of a systematic bicycle company. That is, "We will not buy ready-made CRM, we will develop our own."

Answer 4

Well, learn how it works, what's the problem then?
