Nobody has it all figured out. It sounds pessimistic but it is such a positive thing to know.
Sometimes we look at others and aspire to be them, to know what they know and to do what they do. That’s not healthy. You can learn from them but they don’t know what you know. They’re not you, and there’s only one you.
Each person has a different path. You don’t have to have everything figured out. You just have to know how to find and derive information from the world. You’ll figure out most of it, eventually. Besides, the only one who is supposed to know everything is God.
