Should I pay extra on my mortgage to shorten its term and save interest?

Understand that each month you pay only one month’s worth of interest.  The reason there is so much interest paid on a mortgage is because you are paying on it for so many years.  If you have higher interest loans you are actually money ahead to make minimum payments on your mortgage and pay off your more costly loans.  You can also invest the extra money with the possibility of earning more than you are paying on your mortgage.  This would enable you to pay your mortgage off even faster than making extra payments on the mortgage.
