If having children is in the plan, I will comment that having kids has been much more Schellingy than getting married was, and any life-changes I didn't have solidly cemented before having kids damned sure weren't going to be made after having them.

One thing I'm glad I did was make a habit of trying to write fiction a few times a week before the kids came along - basically, selfishly carve out some me-time - because now I'm still able to maintain this habit with two babies.
