Step 1: Have children.
Step 2: Take a true, deep, honest, soul-searching accounting of your flaws. The things you wish were different. You can “woe is me” here all you like – blame the world, blame your upbringing. Don’t look for solutions. Just make sure you have an honest list of your worst traits.
Step 3: Raise your children to not have those traits. Whatever you said “If only I’d been raised differently…” do that. Blame your parents, go nuts. Just, if you do, make sure you parent your own kids the opposite way.
Step 4: Don’t be a hypocrite. If you tell your children not to do X while you do X, they’ll ignore your words and copy your actions. So as part of raising your kids not to have negative trait X, you have to do everything in your power to suppress that trait in yourself, or you fail at Step 3.
Step 5: Realize that you’ve made tremendous progress in fixing that thing in yourself while simultaneously doing your best to prevent it from ever even developing in your children.
