It seems to me that in my parents home I developed a desire for learning. Part of that was because of my love for my dad [not that he was learning all the time, but rather because of his work in STEM] and also I think this was i response to school where I wanted to do well. It seems to me that this has stayed with me.. I can see this might not be inside every person that might not be driven to learn and learn well. This must be an acquired taste. Thus I think that my experience of tremendous admiration for my dad and the sorts of public schools I went to were unique.
I can see that not everyone has a drive for learning. And certainly I did not either have any kind of drive in this direction except for the set of circumstances I was born into--great parents and great schools and teachers.
To make it clear what I am saying is just a repeat of Aristotle ""Virtue is habit." One ought to accustom himself to learn so that eventually one gets to the point that if a whole day goes by without learning, one feels empty. Almost as if the whole day was a waste.
But furthermore I would like to suggest that there are subjects that are worthwhile learning and others that are destructive to one's mind. \But how can one know what is worthwhile spending time a effort on and on the contrary what is not just a waste of time but destructive before one has actually learned?
I guess one must depend on "authority." Or common sense.
From what I can tell the things that are worthwhile are STEM [Science, Tech, Engineering, Mathematics.] Gemara and Tosphot.
[Though some rishonim (mediaeval authorities)emphasize Metaphysics it is hard to know what is worthwhile to look at in that area.] The problem in philosophy is every professor disagrees with every other professor. You have nothing like that in math where most teachers agree that 2 +2 =4. Philosophy is nothing like that where if one does not downgrade everyone else, then one gets zero credit.
And as far as public schools are concerned, there is no question that my parents would have kept me from them nowadays as highly destructive.
