I recently heard your special hour about the best lessons learned from your parents. The best advice I got growing up was from my Nana, the only grandparent I had, because I'm the youngest of six, born when my mom was 40 years old.
Nana was one of eight children, born in San Francisco in 1901. She experienced the great earthquake of 1906, two world wars, the depression, losing her siblings, her husband, and her only child (my mom). I never once heard her feel sorry for herself or complain about her life situation.
Engraved in my mind, heart and soul is her telling me "This too shall pass." I've had a very difficult year this year, and this advice kept me hanging on.
