A confident gentleman need not be the loudest man at dinner, the most imposing figure at a gathering or the one with the most expensive coat. Confidence is better understood as the ability to conduct yourself properly without demanding constant attention. It comes from preparation, honest self-knowledge and a willingness to take responsibility when something goes wrong. It has very little to do with pretending that you never feel uncertain. Even an experienced man may be nervous before an important conversation. He can still behave well.

Know what you are good at, and what you are not

There is a particular relief in meeting a man who does not claim expertise in everything. He speaks with authority on the matters he knows and listens properly when the subject belongs to somebody else. He can say, “I don’t know enough about that to answer,” without looking around to see whether his reputation has suffered.

This is not false modesty. An accomplished carpenter should be proud of his work. A skilled accountant should not apologise for knowing his profession. But competence is made more convincing by its limits. The person who must have an answer to every question soon gives people reason to doubt the answers he really does know.

Prepare rather than pose

Some occasions are intimidating precisely because they matter. You are meeting a new family, speaking to a room, attending a formal function or beginning an unfamiliar job. The sensible response is preparation. Learn the names you need, consider the dress code, arrive early and think through what may be asked of you.

Do not imagine that confidence requires an effortless appearance. Every good public speaker has prepared. Every thoughtful host has planned. A little work beforehand allows you to be at ease when the occasion arrives. It is far more dependable than adopting a manner which is not your own.

Speak clearly, then allow others a turn

A man who has something worth saying has no need to speak without stopping. Make the point plainly and give others a chance to answer. Listen when the conversation moves away from your interests. Resist the habit of finishing other people’s sentences or turning a colleague’s story into an opportunity to tell a better one.

When you disagree, do so firmly and civilly. You need not soften every opinion until it means nothing, but there is no need to insult a person for holding another view. Being in control of your temper is a far more persuasive sign of strength than winning an argument by volume.

Wear your clothes, do not let them wear you

Good dress helps because it removes an avoidable distraction. A suit that fits, clean shoes and clothing suited to the occasion allow you to attend to the people around you. The point is not to turn an entrance into a spectacle. The best-dressed gentleman in the room may be the one whose clothing is entirely appropriate and consequently attracts little discussion.

The same applies to possessions and titles. They can be pleasant and they can be earned, but they are poor substitutes for courtesy, knowledge or the ability to be useful. There is no requirement to mention what something cost.

Be willing to look inexperienced

Nobody learns a new skill while protecting the appearance of already knowing it. Take a lesson, ask for directions, request help with an unfamiliar task and accept correction without taking offence. The young man who can ask an experienced colleague a sensible question will often make better progress than the one who bluffs his way through the day.

A firm sense of self is compatible with admitting that there is more to learn. Indeed, it depends upon it. The man who cannot bear to be corrected places his vanity ahead of getting something right.

Let other people feel at ease

The finest test of confidence is often what it does to the room. A composed man introduces the newcomer, thanks the waiter, listens to the person who has been interrupted and does not make a joke at someone else’s expense to secure a laugh. He can praise another man’s success without feeling diminished by it.

There will be times to lead, to defend a position and to make a difficult decision. Good manners do not prohibit any of those things. They simply require that strength be exercised with judgement. The purpose of confidence is to be capable of acting well, not to make others feel small.

Be at ease with who you are.

Competence, preparation and good judgement outlast a theatrical display of self-assurance. A gentleman has enough confidence to be decisive when needed and enough humility to keep learning.
