Honest and Trustworthy: Be honest and become a trustworthy person.

Stay committed to your duties: Do your best in your responsibilities, regardless of what others are doing.
Focus on your original intention: Isolate external influences, return to your initial purpose, and concentrate on doing what you should do well.
Do not seek unfair advantages: Do not take advantage of others, even if we are capable of doing so.
Self-reflection: When problems arise, first seek responsibility within oneself.
