Blessed Mother Teresa of Calcutta taught: “God needs our poverty, not our abundance. These are means of being humble:
Speak as little as possible about oneself;- Take care of one’s personal matters 
 - Avoid curiosity;
 - Do not meddle in the affairs of others;
 - Accept contradictions with good humor; 
 - Do not focus on the faults of others; 
 - Accept reproach, even if undeserved; 
 - Yield to the will of others; 
 - Accept insults and abuse; 
 - Accept feeling uncared for, forgotten, despised; 
 - Be courteous and sensitive, even if someone provokes you; 
 - Do not try to be admired and loved; 
 - Do not hide behind one’s own dignity; 
 - Yield in arguments, even if one is right; 
 - Always choose what is most difficult.”
