I was very influenced by Elizabeth O'Connor during the period in which I was attempting to discern whether or not to enter the religious life. Here's something quite wonderful that she said:
Every single one of us has a good work to do in life. This good work not only accomplishes something needed in the world, but completes something in us. When it is finished, a new work emerges that will help make green a desert place as well as scale another mountain inside ourselves.
I don't think by "good work to do in life" she means anything particularly grand as the world would evaluate such work. It can be very hidden indeed or really quite simple. Nevertheless, that good work is something that is truly needed and something that helps us grow interiorly as well.
