From the heart, not the head

I had a picture in my head of where this painting was supposed to go.  But I didn't have the skills to make that picture happen, so ended up with something completely different.  And what does that tell me?  For some reason it makes me think of something a friend posted on Facebook yesterday: 

Don’t grieve over what doesn’t come.
Some things that don’t happen
Keep disaster from happening.

-Rumi

So what "disaster" was prevented by my not painting what I saw in my head?  Perhaps it was just the disaster of painting out of my head instead of my heart...
