My Dad was a career fighter pilot in the Air Force. We got to see lots of the world, but not much of my Dad. As you can imagine his job was demanding.
Because he was away so much, he never got to see me do all those kid things (little league, boy scouts, high school sports, etc).
With two young children of my own at the six year mark of active duty, I had to make a very difficult decision. I loved what I was doing, but I did not want to miss out on all the kid things with my own children. Coming off a shore duty assignment at Beaver Control in San Diego, I decided not to take a set of flying orders back to VQ-3. Reluctantly I resigned my commission.
I still wonder "what if"...
But I was able to stay in the Navy in a Reserve capacity, and watched and participated in all of the kid things with all four of my children.
No regrets.
