I shall not criticize others.
If you don’t like being put down, break any habits you may have of assessing people’s faults. Picking on what’s wrong with someone is often done to make you feel better. Even if you do it behind the person’s back, it fosters negativity, which isn’t loving. Happy people tend not to put others down. Work on yourself! The more self-love you feel, the less likely you’ll be to want to pick others apart. It’s plain not nice, or loving. Find the good in people instead! That will make it easier to also find the good in you!
