You never know what someone is going through. Be kind always.
Being humble can be difficult at times, because every human being wants to be proud of their accomplishments and tell others about their achievements. Even the wealthiest and most powerful people in the world should display humility at all times. Being humble was something that many great people through history accomplished, never believing that they were above average or better than anyone else. Pride is normal, but this needs to be tempered with humility and compassion for others.
