If you had described to me 28 years ago what my life turned out like, I would almost certainly never have married my wife. Who wants children with Aspergers? If you had told it to me 27 years ago, I'd have thought long and hard before proposing; and probably insisted that we never have children.
The mere description doesn't do justice to the reality, and the reality is that I wouldn't trade the family for anything. I'd do it again, except for a few (ok, more than a few) screwups along the way.
And I haven't any idea how I'd convey that fuller knowledge to an earlier me. Some words didn't have the same freight they do now, and I'd no idea how much meaning there could be in "being there." I'd have been scared.
I've not lived a particularly adventurous life, but I remember one moment that was an "OK, here goes" moment--just before "I do." I'll always be glad that I wasn't too scared.
