1. You spend time pleasing yourself, not others.
Being good to yourself is the first step to being good to others without being a people-pleasing doormat. The more you do for your own approval, the more approval you'll get from the people who matter.
2. Your parents know you're the boss of yourself now.
You are truly your own person now, and even if Mom or Dad get all, well, Mom and Dad-ish on you, trust that it's very clear to them that you've got this covered.
