I also feel like this sometimes. And what helps is reading books on the technologies that I want to know about. Even after watching a Youtube video tutorial or following a course on on Udemy just gives a superficial knowledge. That's why I always go back to the books.

When I wanted to learn JavaScript, I watched a few video tutorials on Youtube, but I didn't start to feel like knowing it till I read first few chapters of "JavaScript the definitive guide". Same goes for CSS, it clicked when I read "CSS the missing manual". When I wanted to learn Spring Boot finally, after working on Spring for years I read "Spring in Action" and "Spring Boot in Action".

Its guaranteed that you'll feel smarter after you read a book on any given topic. You don't have to finish the book, rarely you'll implement everything that any book covers. Just go through the foundational chapters. You'll be surprised how many of your peers in workplace don't know about the basic concepts in these books. That's all I wanted to say.
