To succeed in your mission, you must have sin.. A. P. J. Abdul Kalam Quotes
To succeed in your mission, you must have single-minded devotion to your goal.
@Md. Nayan Sheikh Men with lots of thought regarding their aim or mission will not be successful in life. They should think only about their goal. A single-minded devotion means there is only one aim in your life and you are devoted to it. So, if you want to be successful in your life, you should have one mission. And all your efforts should use to make your mission successful.
