As per my opinion, successful people are the most confident person who achieved their goal in a short time. My several friends, cousins, and many more persons are successful in their lives and they are the most confident persons.
Any individual who achieved their dream in a less time in his/her life thus that person is the most confident individual. A most confident person who marry with his or her favourite individual and achieve the top most position or status in the society.
A person who works hard and face several difficulties to achieve his goal in the life thus that person was the most confident person.
