As we all know, a good start is half of success, but I prefer that confidence is the half of success. Confidence is important because it determines how much you achieve in life and those confident will finally succeed as long as they know how to keep persevering and hardworking. Bernard Shaw has said,"Those who have confidence can transform smallness into greatness and make mediocre things look beautiful". With confidence, people can face drawbacks or obstacles with a big bright smile and they will overcome those seemingly insurmountable difficulties. Confidence gives people the determination to work towards those difficult goals, the spirit to bounce back from adversity and the composure to confront their circumstances honestly. I used to feel frustrated even though I was capable of doing the task. Spending all the time in self doubt and self distrust, I couldn't have a correct estimate of myself and overestimate the difficulties I met every time. Later, I realized that I would not achieve in this way, so I began to build faith deliberately. Facing all the difficulties with a positive attitude and exploring my own ability constantly, I found the difficulties are solved one by one and my ability improved day by day. Finally I understood why my headmaster always told me that all I need in my life is perseverance and confidence. With the drive and goal of continuous effort, success is at my fingertips. All in all, we should believe in the proverb:"Where there is a will, there is a way." Confidence is one of the most important abilities of people and it's also the prerequisites of success.
