Looking back, are there experiences your children had that made an impression and helped them choose their path?
Career path, no. But which SA, yes. DS attended summer seminar and it's supposed to be a recruiting tool. Well, it worked. DS is not much of a talker and a pretty straight-forward kid. When I picked him up at the end of NASS, he was talking a mile a minute, and most of it was about what he'd learned about the heroism of this person or that. He was dragging me around to all these places, saying the equivalent of "this is where this great person did this awesome thing." He'd apparently "had a moment" standing in the Hall of (? sorry, I don't even know the name of the building but it's apparently a place that honors former classes and people who have passed on). DS is totally not a "have a moment" kind of person, so as he talked nonstop from Annapolis back to NC, I kept wondering "who is this kid and what have you done with my DS?"
I agree with what everyone said above re: it needs to be your kids' journey and not yours. However, as a naturally hands-off mom, I can say there are downsides to that as well. My DS could have used a little more guidance from me, but I had a huge blind spot when it came to the military. My dad graduated from USAFA, and I was born in the (now closed I believe) Carswell AF base hospital, but Dad left the service when I was really small. My parents and both sets of grandparents met at military functions, and one grandpa was career Air Force. All this to say ... I did not personally grow up with a military lifestyle but the military's influence in my family was just close enough for me to not have considered it for my own children. I always figured DS would end up in some kind of law enforcement. He loves structure, is totally no-nonsense, loves to be outdoors, loves to be active. But he's also crazy-smart and constantly challenging himself (mostly in the realm of physical activities, but also grades). When he first came to me talking about wanting to be in the military, my first thought was "Oh, no!" but my second thought was the realization he'd likely thrive there.
If he'd had a mom (I'm a single parent) who had come to this conclusion on her own and earlier, there are certainly steps I could have encouraged him to take that would have increased his chances and made the path a little more straightforward. Nothing to do about it now for us, but you're in a good spot right now. It does have to be "them," calling the shots for sure, but don't underestimate the power of a guiding parental hand. Good luck to you; your children are lucky to have you.
