One advise I took was from a father of six-tuplets. Asked “What’s the secret to raising 6 kids.” he said, “Don’t have a lot of rules, because if you do, one of them is bound to mess up. So the key is to not have a lot of rules.”
Meaning there’s less rules for you to be happy. You’ll be happier.
This is one of the things A. Robbins teaches. Don’t make it so hard for you to be happy.
