Victorian writer Charles Dickens' quote, "Reflect upon your present blessings, of which every man has many - not on your past misfortunes, of which all men have some," encourages focusing on current gratitude over past regrets. This perspective shift aims to foster contentment and resilience. Dickens, known for novels like 'A Christmas Carol' and 'Oliver Twist,' explored themes of poverty and injustice, drawing from his own early experiences with hardship.
