In total agreement - H and I respond to the “thrilled and excited” question in roughly the same way and for all the same reasons. Now that our Ob/Gyn daughter is finally getting her hands dirty ( pun intended 
) she seems to truly love the work - thankfully. Her choice plays to her personal strengths and academic background and I keep telling myself that she is a great fit. We know a fellow in a different specialty who is doubting their choice and trying to come up with a Plan B. This must be hard in so many ways after putting in so much effort.
My thoughts about D’s suitability for her chosen specialty aside, I can’t imagine maintaining good mental health if life is always a struggle. Hopefully in the future D will be able to pull off a decent work-life balance most of the time even though she has chosen a profession and specialty that doesn’t make it easy.
