In Psalm 147 (which we say every morning in Pesukei D’Zimra), it states, “He counts the number of stars, to all of them He gives a name.” Every star is important enough to Hashem that He counts them and names them. How much more is this true about His humans. Every person is important in Hashem’s eyes.
4. Be kind to yourself. Speaking badly even about yourself is unethical.
