Same here, 39 being in the industry for 14 years. I think this feeling come from the fact that everything around us moving so fast. Old days you can set for months only using Turbo pascal IDE manual without the needs for internet at all. Now literally every few days new technology popups and we are trying to be up to date and we got overwhelmed.I remembered I was trying to learn the new Javascript era and it's zillion frameworks but I couldn't. I think it's better to focus on only one thing and find a side hobby away from the technology.
I too have the same feeling. For me it was Turbo C and later Redhat Linux with its manual and website dump of text files of machine internals for learning to boot up things and program hardware.
Now it is a complete mess of APIs and frameworks with the core hidden deep. It gets so hard to start anything due to this and the interest evaporates very fast.
I agree with most of your sentiments but would argue it’s better to focus on only “one thing at a time” than exclusively “only one thing”.
But that’s personal preference and I certainly admire individuals who are able to “focus only on one thing”.
