Down and out in a sail boat

I felt a little "shallow" sharing my dream to make a living on a sail boat. Especially with my sister showing me art work of children in Africa needing support to attend school. I immediately thought of Mbuma, a child I met in Africa. He asked me "Don't forget me...I want to work in America".
My daily Pray As You Go pod cast was about Jesus encouraging us to be like little children, to abandon our worldly desires. I thought to myself "Crap! Now I really feel shallow". In my drawing/journal I questioned the difference I have made over the past year.
Yet, when my sister asked if I would help the children in Africa I said "I'd be all over it like a kid on candy".
Maybe the flexibility of freelance work would help me be available for volunteering? Does this make sense, or am I just fooling myself to not feel so shallow?
