When I was about 14 years old, for the first time in my life, a teacher wanted all the students in the class to write something on what we want to be in future. The very first thought that came to me was that my future course is entirely in the hands of God and I am not the one to fix a goal to achieve in my life.
I nevertheless knew that no one would ever appreciate such a reply. So, I wrote, after extrapolating my life status at that time, that I would want to become the principal of a school one day, without any internal conviction!
I never became a principal. But God has indeed acted as per my conviction and I am in the process of becoming what He wanted me to be, I hope!
