The way of a fool is straight in his own eyes/ every fool has his own way
The fool is confident in his actions and in the path he walks, while the wise man knows that he must listen to advice and learn from the wisdom and experience of others.
("The way of a fool is straight in his own eyes, but a wise man listens to advice" - Proverbs 12:15)
