There is no right or wrong...
This is not a how-to guide. I honestly don't think it would matter how many teenagers you brought up, you will never become an expert. Everyone is different, including children and young adults. You will not get it right all the time. Fact. You might as well accept it now. There is no room for perfection in any aspect of parenthood, but luckily, children don't actually care about perfection, they care about happiness and security. The good news is, you can give them that without being an expert, you just need to walk a mile in their stinky trainers now and again.
