A man without an aim, is like a ship without a destination. Every single person must have an aim. I too have aimed to be a doctor. A doctor is not just a professional but someone who gives a new life to others, someone not less important than god. It is a profession of great respect and nobility. To become a doctor one needs to work hard.
Sure without hard work,you can't taste success. I too swear that I will work hard to achieve my aim. I will devote my life to the service of the needy and sick. I just hope god will help me on my journey towards goal.
