The quote "Without love, we are birds with broken wings" from Mitch Albom's book, "Tuesdays with Morrie," highlights the essential role of love in human existence. It suggests that love is fundamental to our well-being and happiness, implying that, without it, we become incapacitated and unable to fully experience life. The metaphor of broken wings evokes a sense of loss and longing, emphasizing that love provides us with the strength to rise and thrive.
