Be Humble Day is observed on February 22, 2023. Please use this day to don't talk about your success and how perfect you are. Just be humble - and keep silent! You should do exactly what Be Humble Day tells you to. This is not a day to randomly blow money, but to be pennywise. Sober food, modest clothing, no branded goods is the motto of Be Humble Day. Maybe leave your fancy car at home and take the bus instead.
Humbleness is also called modesty and means a behavior on which people do not claim all too much for themselves. Sometimes that includes to forgo something and to not take full advantage out of something. Most often Be Humble Day means to quit for the sake of others and to be anything but a show-off kind of person.
