I could have answered this question in many ways, depending on which year I was writing. Since it’s now 2018 (my daughter finished undergrad in 2014 and MM in 2016) I have a longer perspective and can see that some things I would have done differently several years ago turned out not to be mistakes after all. Of course, my perspective may shift again several more times. There were moves we made as parents that I deeply regretted a few years ago but that I now see as strokes of good fortune and blind luck. There’s so much I could say, but can’t in a public forum about particular situations.
