From the excellent DailyOm site, passed on by our friend Thalbir:
"Sometimes it takes us the better part of a lifetime to discover our lifes work, even though we may have been doing it our whole lives without necessarily realizing it. Our lifes work is not always what we do to make money, although we often think it should be, and sometimes this way of thinking prevents us from seeing clearly what it is. It may be the work of having children, caring for them, and running a household. The way we know our lifes work is by how we feel when we are doing it. When we are doing our lifes work, we feel an uncanny sense of ease and alignment. This doesnt mean that the work is always easy, and it doesnt mean that its the only work we have to do; it just means that there is a conviction deep inside us that tells us we are in tune with our innermost self.
"When we are engaged in our lifes work, our bodies feel more alive, because our energy is devoted to a cause that, in turn, feeds us. We may be tired after engaging in our lifes work, but we are almost never depleted. We feel grounded in the world, knowing that we belong here and have something important to offer. When we are deeply unhappy, depressed, or subject to one illness after another, this may be due to a sense of disconnection from our lifes work. At times like these, finding the work we are meant to do is an essential act of healing. Most of us remember a time when we felt fully engaged in some act of work, service or creativity, and it is here that we may rediscover the work we are meant to do now. On the other hand, it may be time to explore what inspires us through volunteering, taking a class, going back to school, or just doing whatever it is we long to try. We all have callings, and when we find them, we owe it to ourselves to nurture and protect them, because while they may or may not be our livelihood, they are the keys to our wellbeing."
