We each have a passion for different things. This passion can vary from person to person and also seem to change with the evolving age of an individual. The girl who used to play with dolls and built dollhouses with friends as a kid might grow a passion for music or driving cars as she grows up. Passion varies from hobbies and interest. It is an interest at another level where one needs to take care of the object one is passionate about. Just like someone who loves playing guitar and understands the quality and importance of a good guitar would do everything needed to protect the instrument from any sort of damage.
