When I was young (teens) I really did think I would have kids. Then, when I got married we decided we wouldn't. I was 27 and in a PhD program. I was going to be a "professor" and my life would be filled with that. Then one day I was in the ASU bookstore and I got mesmerized by the books on pregnancy and babies. I had to have one. It was a bit of a long road, since I lost my first baby, but I did have 2 kids.
Truthfully, I was better with them as they grew. Don't mistake me, they were planned and very wanted, but I knew my limits. My husband stayed home with #1 for almost a year and I always joke those were the best days of my life! I always worked and didn't just center my life around the kids. We always had an active social life, too. As they grew, I spent more and more time doing things with my kids. They grew up to be very sociable and emotionally intelligent, wonderful adults. I always say that I must be sort of an OK person, because my kids turned out so well.
So, what I am trying to say is that while a lot of parts of parenting aren't super fun, it is what you make it. What I resented were the "super" parents who just did nothing but focus on their kids. I hated seeing them at sports things or other activities. There were even some of these parents, mostly dads, at the junior level cycling events that my younger son did.
