Not sure why, but I've been on this kick to read the classics instead of the latest hyped up drivel.
On this, I had the pleasure of reading Baltasar Gracian's "The Art of Prudence". He was a Spanish Jesuist, and the book (published ~400 years ago) is essentially a set of ~300 maxims - on how to live your life. Tons to pick from, but some that spoke to me included:
Princes like to be helped, but not surpassed. Advice should be offered a reminder of what they've forgotten, not an insight they've never had.
The truths which matter most are always only half-spoken
God himself punishes not with the rod, but at the opportune moment. "Time and I against any other two"
Moderation in all things - an orange squeezed too hard leads to bitter juice
Each individual is born a barbarian, and is saved from being a beast by acquiring culture
There are mirrors for the face, but none for the spirit; let discreet self-reflection by yours
There is no honest dealing with the dishonest since they feel under no obligation to integrity
Be mad with the crowd than sane all alone
It is as necessary to study people as it to study books
The wise have always been the least patient, for as knowledge increases, so does impatience
Pride yourself on the fact that if gallantry, generosity and fidelity disappeared from the world, they could be found in you
A statue on an altar will never be venerated by someone who it as a tree trunk in a garden
Someone is truly wise who is wise once they're in the saddle
Spend the first part of a fine life in commune with the dead. We are born to know, .. and books reliably turn us into people. Spend the second part with the living. Let the third stage be spent entirely with yourself: the ultimate happiness, to philosophize.
Whoever has told his secrets to another has become their slave
Former friends make the worst enemies
They say that our nature changes every seven years
Even princes need those to write, and they fear their pends more than ugly women fear artists' brushes
My book was full of markups -- definitely worth a read.
