Learn to restrain anger. It’s probably a good idea to focus on removing story-tellers (liars) and slanderers (people who gossip and talk negatively of others) from your circle. Anger can be intoxicating. People tend to react when angry as opposed to act tactfully – once free from the emotion and rage that is anger.
Keep good company. Your own self-respect and habits of courtesy will be lost if you keep low company. However, in good company your gentlemanly virtues will be cultivated and become habitual.
Keep your engagements. Nothing is ruder than to miss an appointment or be so disrespectful as to show up late. This does apply to BOTH business and pleasure.
Avoid arrogant personality. There is simply no room in a gentleman’s profile to mock, ridicule, or look down upon anyone. It is not the job of a gentleman to highlight non-gentlemanly behavior of others. Rather, remove them from your circle and pursue your own virtues of proper gentlemanly deportment.
Make it a habit to not only be punctual, but to also be respectfully early for your engagements, both busines and social. Being late leads to rushing and hurriedness, both of which are disrespectful to the person(s) you are meeting.
