I mean you won't find the ultimate answer, but I found the writings of Oliver Burkeman on these kinds of topics interesting. He's a bit of an anti-productivity guru (aka recognizing that these are important issues, but being highly critical about the usual "read my book and everything will be fine" type of people).
