Original sin is the fallen human nature that we all inherit because of the first, or "original" sin of Adam and Eve, when they ate of the tree of the knowledge of good and evil. We did not commit original sin, Adam and Eve did. We simply suffer the effects of it.
Personal sin, on the other hand, is a sin that one actually commits. The guilt from original sin is not our fault. The guilt from personal sin is.
