If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
No, I definitely didn't learn everything I think I need. I am very much in need to learn a lot of things, desperately, in fact.
I still pursue knowledge from pragmatic standpoint. "This is useful, this is not, therefore I need to learn this and can completely disregard that". There is just no "drive" in it, no genuine force of curiosity that used to be so motivating. From pragmatic standpoint, my ability to learn suffered a great hit.
Have you tried to look at any new areas recently? Perhaps you are getting kind of "bored" by the repetition.
