Eh, my H is a very successful engineer. None of our three lads wanted anything to do with engineering. Both of my parents were music teachers (instrumental). I certainly never inherited an instrumental music gene, though did inherit the teaching gene - just math/science instead. My parents can’t fathom wanting to be a math/science teacher.
In bygone days kids did what their parents did. It could be why most of those 85% hate their jobs. In today’s day and age we know just how different many of us are from our parents. 'Tis a better world for that IMO. I tell kids at school to find a niche they enjoy and fill it. Many do.
