Profession as passion

When I was a little kid I love watching white gowns the nurses and doctors wearing I always put in my mind someday I will be the greatest doctor but as time goes by my perspective change. My daily routine must follow my schedule, I become time conscious and worst I calculate every move I make. I still remember I ask my papa "why car moves? when there is gravity that pulls everything?" he simply said the bright boys invented those things. My curiosity grows as I enter college I have a lot of questions in my mind number one is I wonder why is it possible that fuel makes the car move and what are behind those metals? so I decided to explore in my curiosity and like wow! my heart belongs to the profession I choose I become eager to learn more and more.
