If this is a legit question (and I ask because nothing good can come from presenting that question to a man) here’s a 3-part answer:
1st, the secret to aging well is to be beautiful for your age. Don’t compete with women younger than you because they aren’t competing with you. They are just living their lives being young and gorgeous and it’s a great place to be navigating the world from. Start with and love where you are. Be healthy, do what you love, find your people, and craft a life you love and you will shine.
2nd, your 30s are a decade of being a woman. Prior to 30, most females are still girls. There’s a lot of advantages to being a girl, fearlessness, youth, anticipation, fun, gorgeousness (see above), but there’s real power in becoming a woman. Women find themselves, embrace their bodies, prioritize their future, and make massive meaningful strides in their 30s. Enjoy becoming. Focus on what you have and what you are finding as opposed to what you are losing. In your 30s, you can layer confidence, knowing, and contribution to your beauty and that’s powerful and fulfilling.
3rd, celebrate others for who they are, not what they look like. There are some stunningly beautiful people on the planet and even then, that’s not who they are. Women will hear commentary about their looks from birth to death, from people they love, people they don’t like, and everyone in between. The commentary doesn’t tell the story of who they are, what they will become, if they are a good person, fantastic mom, or qualified to lead. Practice celebrating your life and your girlfriends lives for any other reason, for many other reasons. Connect with others on a deeper level and watch your perspective shift. Good luck!
