Ponderings on "I"

They say that "I" get the blame for anything wrong, or sinful, that I do. Then they say that when I do something right, it's not me, but God that gets all the credit. Somehow, this bothers me.
Don't get me wrong, I believe that on my own I am incapable of doing good, but I see the same paradox here that I see in salvation. I can do nothing to "earn" salvation, but I have to assent, or make a choice of the will, before God will save me. I think a similar choice must be made in all of life. While I, on my own, cannot become good, I have to be willing to let God work, and striving to make my life fertile soil for Him to work in.
