Did you retire because of luck or did you earn it? Fortunate implies luck.
By the way...I am jealous. LOL
We had good jobs and saved between 36-38% of our gross income for 20 years. The one bit of good luck that came our way, if it can be so crassly put that way, is that an elderly aunt passed away and left my husband her house and money. We gave the house to my stepson and the money to my stepdaughter.
