I would keep it simple. Read autobiographies or biographies of people. Read a lot, it will give you a sense of what people did in life, what habits they followed and how they lived.
There are also some really good books written in recent times, you can scrape for book recommendations by people you admire. Some of the people I admire are Elon Musk, Bill Gates,
Most importantly ask yourself, what kind of life you want to live for yourself.
And remember, most of advice online is bullshit, and most of them are repeating the same thing in different ways and making money from it.
You have the power to design your life
While you are at it, remember that you are just a speck in the infinite universe. You are already dead, it happened the moment you were born, every passing second, you are slowly getting closer to the grave.
