An old friend of mine, Merriam Webster, describes you as an activity in which one exerts strength or faculties to do or perform something. If that is the case, then I guess I have known you for almost all of my life.
A lot of people refer to you as Job, while there are others who call you Parenting. Those who treat you as a selfless act call you Vocation, while most of our minors call you Studying. Some think of you as their passion, while others see you as just a means to an end. You bring satisfaction, but you also bring frustration, lots of it at times. You are constantly here, there and everywhere. What do we make of you?
