Why do we call hindsight a benefit?

I just logged onto my blog as it’s about time for another post, with no idea what I was going to write about, and stumbled across a list of recent posts on blogs I follow, with links. How did I never discover it before now?
That happens to me so often with technology, which I make no claims to have mastered, and – even more galling – with life. It’s always struck me as a devastating stroke of irony that we learn from experience, because there are situations in life where we need to acquire knowledge before the experience and, once the experience is over the knowledge becomes superfluous. If only I’d known something – anything – about parenting before my children arrived. Yes, I learned a lot about parenting through being a mother and, with the uncomfortable benefit of hindsight could do it all so much better now…
Writing encapsulates the sting of hindsight because once a book is published you can reread it – and it’s too late to change anything! As a rule I’m not one for looking back with regrets, but I wonder if other people’s stories turn out exactly how they want them to be.
Would you change anything about your writing if you could turn the clock back?
