It takes a lot of humility and strength to admit this. Kudos to the author.

I was similar to that in the past, chasing tutorials and only having half-baked knowledge. What shook me out of that was this article: https://fabiensanglard.net/c/

    I'm going to start with the things I didn't take too seriously: Internet tutorials, blogs and almost anything brought by Google (yes, it includes this article). I usually considered those sources unreliable and potentially harmful.

    Like a lot of people in the industry I used to Google way too often. Overtime I found the illusion of speed and the inaccuracy of the answers to be counter-productive.
    
    No website is as good as a good book. And no good book is as good as a disassembly output.

This set me straight and got me to look into actual authoritative sources. Instead of tutorials read a proper book. Don't scrape StackOverflow, read the reference documentation. Learn to write automated tests instead of randomly poking around in the application. The thing is, I did not even intend to learn C, but after reading that article and other articles on that website I accepted that if I want to get good at programming I should start with the fundamentals, and C was a good starting point. It was the first language I actually learned properly.
