Does God Get Disappointed?

Here's a quote from Obama on disappointment and motivation:

"I'm not a shouter. I find that what was always effective with me as a kid, and Michelle and I find it effective with our kids, is just making people feel really guilty. Like 'Boy, I am disappointed in you. I expected so much more.' And I think people generally want to do the right thing, and if you're clear to them about what that right thing is, and if they see you doing the right thing, then that gives you some leverage. Hollering at people isn't usually that effective. Now, there are exceptions. There are times where guilt doesn't work, and then you have to use fear."

Does God motivate us with guilt and disappointment? Disappointment generally has a lot to do with failed expectations. Do we fail to meet God's expectations? Are commandments and expectations the same thing, because obviously we fail to obey his commands? Disappointment in our culture is viewed as a positive thing (as exemplified by our President), but is it really a creative force that enables people to fulfill their purpose?

I've had this conversation with a number of people lately and I'd love to hear your thoughts on it.
