One of the best things that will ever happen to you.
Mr Peabody's Wayback Machine: 2004 I got surprise nuked as head of product development at my own startup! WTF?
Started looking for jobs, but fortunately decided instead to use my Babson MBA and do my own financial advisor thing and spend 2 days a week helping raise grandchild. Big help to 2 working parents. That and volunteering as a math/science teachers' helper at local middle schools worked out great. Big transition from long hours, high stress career which strangely I'd loved.
Flash fwd to 2025/6 and 1st granddaughter getting masters* in Bioinformatics and listed as co-author in published papers. 2nd one is at Tufts EE like both grandfathers and MIT EE Dad. Off to 6 months at Oxford junior year next month. You can have a major opportunity to help guide the lives of kids as a grandparent. If I had grandsons I'd encourage them to consider the trades vs college.
* As a freshman in college, she's playing beach football. Guys ask, "Where'd you learn to throw a tight spiral like that?"
She replied, "My grandfather." My proudest educational moment.
