Credit score

I paid off my house.  4 months later I start seeing negative comments about my credit history for not having any experience with a mortgage and I lost points because of it!  Just goes to show you exactly how asinine this whole FICO SCORE crap is.  I am very close to being completely debt free.  Never again.  Not one red cent will I EVER go into debt.  You do NOT need a "credit score"  to thrive.   Once my remaining two credit cards are paid off, you can bet, my "score"  will tank for lack of activity.  So be it.  I refuse to be a slave on the plantation of debt.
