All great human deeds both consume and transform their doers. Consider an athlete, or a scientist, or an artist, or an independent business creator. In service of their goals they lay down time and energy and many other choices and pleasures; in return, they become most truly themselves. A false destiny may be spotted by the fact that it consumes without transforming, without giving back the enlarged self. Become a parent is one of these basic human transformational deeds. By this act, we change our fundamental relationship with the universe -- if nothing else, we lose our place as the pinnacle and end-point of evolution, and become a mere link.
