Find a certified financial planner or the equivalent in your country (but walk away immediately if they start trying to sell you on whole life insurance or some other scummy products). You want someone who will act as a fiduciary and give you sound financial advice that's for your benefit and not theirs. At a young age, having that grasp of some financial concepts like what it takes to retire, what kind of emergency fund you need, how to protect your money from taxation as much as legally possible, what your budget should look like compared to other financially sound individuals, etc will make your life so much easier. I can't give you any advice beyond "seek out a fiduciary of some sort" because I don't know the specifics of your country in, however if you can save and invest instead of burying yourself in high interest debt, you'll be doing future you a huge favor.

Also, travel while you're young and don't have kids because they'll take up a lot of time and it's difficult to travel with little ones.

Take care of your whole body. This includes your eyes, ears, teeth, mind, brain, and all your extremities and vital organs. Eat a variety of nutritious foods at appropriate calorie levels to maintain a healthy weight, brush your teeth, do your cardiovascular exercises and resistance training, and see a doctor and dentist regularly.

Stick with school, especially if it's free. It is hard paying off debt from school without a degree to help you.

Love yourself and those around you.
