Start therapy or some sort of personal coaching the moment your child is born and keep doing it regularly. Every session has made me a better parent, sometimes because I learned something explicitly about parenting, but more often because I suddenly resolved some deep dysfunction that had made life unreasonably difficult. I only figured this out 9 years in and I regret not starting earlier for my and my kids' sakes.
