I think anger is a good motivator, at times. Recently, the few times I have reached a boiling point, acknowledged my anger, and let it out (not always in the nicest way; but with adult maturity), I was able to change my situation for the better. Unfortunately, for me I also have a tendency not to realize/admit I'm angry and it creates a BIG obstacle in healing my relationships. I also sometimes feel anger when what I am actually feeling is really something else. I'm not always good at finding the root problem.
