An excellent passage on wisdom from The Bible. The Book of Wisdom is a great source of common sense advice. Ch6:Vs12

“Wisdom is radiant and unfading,

and she is easily discerned by those who love her,

and is found by those who seek her.

She hastens to make herself known to those who desire her.

One who rises early to seek her will have no difficulty,

for she will be found sitting at the gate.

To fix one’s thought on her is perfect understanding,

and one who is vigilant on her account will soon be free from care,

because she goes about seeking those worthy of her,

and she graciously appears to them in their paths,

and meets them in every thought.

The beginning of wisdom* is the most sincere desire for instruction,

and concern for instruction is love of her,

and love of her is the keeping of her laws,

and giving heed to her laws is assurance of immortality,

and immortality brings one near to God;

so the desire for wisdom leads to a kingdom.

Therefore if you delight in thrones and sceptres, O monarchs over the peoples,

honour wisdom, so that you may reign for ever.” What is your favorite line in this Scripture?
