Victory Incomplete?

So when I struggle with sin pattern in my life (like maybe losing weight or sticking to a financial budget), is the fact that I'm not completely victorious yet evidence that my victory is incomplete?  Or is it instead evidence that I am trapped in sin?  Am I trying to justify my own sin, waiting for someone else (maybe God) to take responsibility for it and give me victory over it?  (1 John 3:8-0 & notes.)
