Not a therapist, but would probably switch my life with yours in a second. I am the same age as you, in tech in a third world country and working two jobs and eighty hours a week to afford a good future for my kids. I will have to probably keep doing so into my fifties to give them a good education. Bottom line, it might be a matter of perspective.

Wondrium/The Great Courses has a number of good quality courses on Anthropology taught by renowned professors from the US. I have a subscription and a passing interest in anthropology that has been satisfied by the above. YMMV.

The last time i checked India wasnt strictly an adjoining region of Afghanistan.
roundthecorner commented on Ask HN: Have you ever worked hard on something that did not pay off? · Posted by u/arduinomancer
In my experience a better question would have been.
"Have you worked hard on something that DID pay off???"
Most of the things that we work hard on never pay off except in terms of learned lessons.

roundthecorner commented on Ask HN: Am I the only one feeling stupid when looking at interview questions? · Posted by u/questionguy1
I am working as an architect with about 17+ years of experience and i feel the same. However it would still be prudent to practice as mentioned in one of the comments. Things seem easier if tackled before. Your task should be to create the time and the motivation for regular practice.

If you want a broad overview of how RDBMS work under the hood, "Designing Data Intensive Applications", would be a good conceptual start.
This could be followed by database internals books like "Expert Oracle Database Architecture" and "Pro SQL Server Internals", irrespective of whether you use these databases or not, you will learn a ton of stuff about database internals and system design.
If you are interested in database schema design etc, then look up "The Database Model Resource Book" Volumes 1,2,3. None of the above are quick reads but they are solid foundations for becoming a well rounded DBMS professional.
