Everyone chooses their own path and no one is truly able to judge the path that others take.
I have experienced no greater, more joyful time than the birth, infancy, youth and adolescence of my children.
They certainly did not increase my financial assets. They have neither assured nor expedited my retirement.
Our only currency has been love.

You have been blessed; however, with the best will in the world, parents can be short-changed and so can children. We must remember that our kids are separate people and through no fault of the parents they can go astray and give grief. If you are a good parent, well, of course the chances of rearing good offspring are good but sadly not guaranteed. I do accept that it all worked out for you though.
