Negative traits and their positive meanings:
Guilt : To err is human. But you should accept and learn from your mistakes too. This acceptance will take you closer to the ultimate truth.
Blame : Take the responsibility of the world. You might not be directly associated with the problem but taking its responsibility will make you stronger.
Anger : You need to see the world more because there are a lot of good things happening elsewhere too. Embrace that positivity.
Irritability : Ignore if something is bothering you. There are better things in life. Focus on these positive aspects.
