You're correct that I'm in a comfort zone. I can read about why these tools are useful. At the same time, these are tools that solve problems I don't have. How can one practice them like that? My mind is blocked here, I'm unable to come up with situations even "for learning purposes", for side projects, scenarios that would let me understand them better.
I have difficulty coming up with new problem scenarios in my head, unless they resemble something I already encountered in the past. I will have to overcome this, if I were to become a better engineer.
Without having a problem scenario, there's no work to be done. So there's only the job hunt right now.
