Working through a painting

When I start painting I have no idea where it will end up. Sure I have a plan in mind, but when I going it always takes me somewhere else. It is like riding a horse that does not know you yet. The horse has not grown acclimated to your touch and does not respond. I say lets go here and the horse says no we are going somewhere else. I have to go where it tells me to,

I would even go so far to say that being an artist is always being led around by someone else.

You just have to go where they say. And I dont know what is leading me. My past experiences, my skill, my emotion, or something else

That is the joy of it all too. I don't know where we are going so it is always new and an adventure.
