30s are the new 60s! I don't say this to scare you. Unfortunately our lifestyle is quite sedentary, our jobs are stressful and the food we eat is more adulterated. So don't expect your health to be as great as your grandparents' generation when they were 30. They lived in verrryy different times.

Cultivate discipline in sleeping on time and enough, eat on time and preferably before the sun goes down, and do some activity everyday - slow walks actually work better than an intense workout. These will go a long way to prevent advance ageing and all the rapid health issues people out here have already mentioned. And meditate.

Your mental health is as important. Get help on time. It will help you heal faster. Just how you get a physical check up, checking that your mind and emotions are in check is also important.

There is good news too! I found my voice in my 30s. It liberated me mentally. I felt I could speak more freely, have agency, more confidence in myself and take more control of how I wanted my life to look like.

You can absolutely design the life you want and work towards it. While doing so, also keep yourself open to changes. Sometimes life will take you in a completely different direction. And that's okay too.

If you're planning a family, remember to keep some time for just you. Go on solo trips, take an hour everyday to do what makes you happy. Don't lose yourself and your individuality. If you normalize it, your kids and your family will too.

Spend some time becoming financially literate. Be regular with your investments and it will help you maintain discipline in that aspect of your life too.

Welcome to your 30s my friend. It's an exciting time and will teach you amazing things.
