I think this is exactly right. Even the conscious part of you, the part you perceive as being "in control" isn't really. Free will is an illusion (but a very compelling one!) This realization, too, can help you make better decisions. For example: I've found it helpful in reducing my consumption of sugar. I didn't decide to love the taste of sugar. That's something that just happened to me, like depression. So it's easier for me to resist the urge to snack if I think of the cravings as an attempt by an "external" agent to control my actions, even though that agent is physically located inside my own brain.

This idea even comes with a catchy slogan: sometimes your brain has a mind of its own :-)
