When I wrote the poem below, I thought I had come to clarity on this question. However, it continues to repeat like endless waves lapping at the shore. I have to stop and remind myself that as long as my choices bring me joy and lovingly connect me to the world, they are part of my purpose ... they are part of the sea of "perfect possibilities."
I no longer believe I should pack up and go serve the starving children in Africa. While that could be soul satisfying, there are other projects that fit my life and skills better.
The less dramatic project under contemplation could serve people and perhaps there are ways to increase the possibilities for contribution. Maybe that's the real issue ... finding ways to do what we love and fits our skills and talents in a way that serves others.
