Quote by Orson Scott Card
When you have wisdom that another person knows that he needs, you give it freely. But when the other person doesn't yet know that he needs your wisdom you keep it to yourself. Food only looks good to a hungry man.
Summary
This quote suggests that sharing wisdom is only valuable when it is recognized and appreciated by the recipient. If someone acknowledges their need for wisdom, it is beneficial to offer it openly without hesitation. However, if someone is unaware of their need for wisdom, it may be futile or unappreciated to share it with them. The comparison to food and hunger implies that wisdom is most appealing and relevant when it fulfills a recognizable need or desire.
