Are you radically different than your younger self? Are there key elements that have stayed the same? Most parts? Do you feel as if you've followed the "roadmap of life" or forged your own path? Have there been "chapters" or do things all sort of slide into one contiguous flow? Share what you'd like!
Chances are you would have been a worse parent 10 years earlier; full of energy, but not enough experience to know how to parent well, and perhaps harboring a secret resentment for crushed dreams.
10 years later, those dreams are already achieved/crushed and those kids are the next big project in your life that you can pay full attention to. When you're caffeinated, of course.
