Don’t say you don’t have enough time. You have exactly the same number of hours per day that were given to Helen Keller, Pasteur, Michaelangelo, Mother Teresa, Leonardo da Vinci, Thomas Jefferson, and Albert Einstein.
You know what’s the worst? When you’re just trying to be nice and what you get back is nothing. I can do with positive or negative reactions. But to say absolutely nothing? You’re just saying I’m not worthy of a response to “how is your day”. And does anyone deserve that?
