Intelligence, honesty and a sense of humor

At our English club lesson Davit Nikoghosyan tried to define the most important traits of character for a person to possess if he/she wants to be a success. The question was formulated in this way: "In your opinion, what is the most important characteristic (for example, honesty, intelligence, a sense of humor) that a person can have to be successful in life?"

Here is Davit's answer: "I  think that a person should have different traits of character in order to be successful. At first I would like to mention that honesty, intelligence and a sense of humor can help any person. If a person is engaged in trade, honesty can broaden his/her reputation and increase the number of clients. I myself appreciate combining intelligence and honesty, because intelligence provides constant relationship, and honesty makes people get closer to one another. On the other hand, life would be so boring without a sense of humor."
