One of the basic principles of Judaism is that we are to constantly work at self improvement. We are supposed to make daily character checks to see how we can treat people better, and work at getting closer to Hashem.
One idea that might help in this area, is to remember two pairs of words that rhyme as a quick reference guide. They are קנאה-שנאה and גאוה-תאוה.
The word קנאה means jealousy. We must not allow ourselves to be jealous of others, but we are to be happy with our lot in life. שנאה means hatred and we are to overcome such feelings and work to love every Jew.
The word גאוה symbolizes pride, conceit, and haughtiness. Everything we have is from Hashem and humility is the goal to achieve. And תאוה refers to lusts. This can come in many ways. We can lust after money, honor, food, women, a fancy car, or large house, etc. We have to learn to discipline ourselves and not give in to such lusts.
Perhaps remembering שנאה-קנאה and גאוה-תאוה, will help us succeed in our quest at self improvement.
