I don't particularly look at age, how about a few things that really opened up my mind instead?
Schopenhauer is definitely worth reading; okay, maybe aside his views favouring the submissive woman and favouring eugenics. We already practice eugenics because we want to be with someone of quality; but, suggesting Plato's idea of castrating non conformists and sticking idiots in an asylum is going a bit too far. Relationships based on dominance: ugh, don't get me started on how much they disgust me.
Check out Nicomachaen Ethics of Aristotle. He speaks of the importance of temperance; note this is ancient Greece where the notion of moderation is to find that special spot where everything is all nice. He continues to explain different forms of friendship and what to expect from those relationships; much of his writing in these books is forward thinking by today's standards. Aristotle is a difficult read; but, you could always watch lectures online.
Steven Pinker has written some really cool things regarding the nature of language, the mind and doesn't spoon feed his political ideologies like Noam Chomsky does. Plus; he's a brilliant writer. I'm reading his Language Instinct and another he's written on the structure of words.
Introduction to logic; Irving M. Copi. I bought this little gem at a thrift shop not long ago; and, it's a wonderful little text book on logic and critical thought. Also, try Understanding Media by Marshall McLuhen. And, if you can score a copy The Became What They Beheld by Edmund Snow Carpenter.
The Conquest of Happiness, Bertrand Russell. No psychobabble nonsense; just good advice.
Literature wise:
I have suggested the John Steinbeck might be ISFP. I haven't finished East of Eden yet; misplaced it. Winter of our Discontent and Of Mice and Men are genius. I often recommend The Stranger/The Outsider of Albert Camus; I'm always curious to how people react to Meursault's character. I've had people express sympathy, others like myself relate, and others lash out with disgust.
Forum wise:
Don't limit yourself to your type. Use MBTI, Kiersey, etc. to undrestand others and to get to know your own motivations. I know what sort of people I want for lovers; who I want as friends, coworkers or acquaintances. We've been making these assessments long before we knew of MBTI; so, it matters but it doesn't really matter either.
