COMPLETE and FINISHED

Some say there is no difference between COMPLETE and FINISHED. Please explain the difference between COMPLETE and FINISHED in a way that is easy to understand.

Here is his astute answer: "When you marry the right woman, you are COMPLETE. But, when you marry the wrong woman, you are FINISHED. And when the right one catches you with the wrong one, you are COMPLETELY FINISHED!"
