The Chazon Ish (20th century Israel) described the level a person is potentially capable of attaining if he has a long term goal for self-improvement: "If a person constantly strives to improve his character traits, it is possible he will eventually reach a level that he no longer gets angry, will not feel hatred or resentment, will not take revenge nor bear a grudge, will not have ambitions of seeking honor, and will not desire mundane pleasures."
Today, view every person you find difficult as your partner in character development. View every encounter as an opportunity to develop your positive qualities.
