Proverbs 14:8
The wisdom of the prudent is to understand his way: but the folly of fools is deceit.
Luke 14:28-32
For which of you, intending to build a tower, sitteth not down first, and counteth the cost, whether he have sufficient to finish it?
Lest haply, after he hath laid the foundation, and is not able to finish it, all that behold it begin to mock him,
Saying, This man began to build, and was not able to finish.
Or what king, going to make war against another king, sitteth not down first, and consulteth whether he be able with ten thousand to meet him that cometh against him with twenty thousand?
Or else, while the other is yet a great way off, he sendeth an ambassage, and desireth conditions of peace.
Ecclesiastes 10:10

Wherefore is there a price in the hand of a fool to get wisdom, seeing he hath no heart to it?
Luke 12:18-20
And he said, This will I do: I will pull down my barns, and build greater; and there will I bestow all my fruits and my goods.
And I will say to my soul, Soul, thou hast much goods laid up for many years; take thine ease, eat, drink, and be merry.
But God said unto him, Thou fool, this night thy soul shall be required of thee: then whose shall those things be, which thou hast provided?
