Quote of the Day by Immanuel Kant: Immanuel Kant's quote, “Unless children, and especially the children of rich parents and princes, are made to realise that they must work, they remain children all their lives,” highlights the importance of hard work, discipline and responsibility in shaping mature individuals. Taken from Kant on Education (1803), the quote continues to offer valuable lessons on parenting, education and personal growth, reminding readers that true maturity comes through effort rather than privilege.
