Foolish: How foolish am I? when was the last time someone called me foolish? It's better to be foolish in the eyes of the world than God.
The Parable of the Rich Fool: (Lk 12:16-21) In this story the rich had a bountiful harvest. he had ro pull down his small barns to build larger ones so to store his harvest. After that he congratulated himself on his achievements: ..'rest eat, drink be merry as you have stored  so much for many years!'... But God said to him 'You fool, this night your life will be demanded of you; and the things you have stored, to whom will they belong?'. God is the source of all blessings so are we not obliged to share not only the surplus with others?
The Parable of the Ten Virgins: (Mt. 25:1-13) In this story the kingdom of heaven is compaired to ten virgins who took their lamps and went out to meet the bridegroom. Five of them were foolish and five were wise. The foolish ones when taking their lamps brought no oil with them but the wise ones brought flasks of oil with them.. after a long waiting the bridegroom finally was announced. The wise ones trimmed their lamps but the foolish ones have to go to buy oil and so could not meet the bridegroom when he arived.

To be called foolish by the world is better than to be called a fool by God so be prepared always!
