Don’t know your dream
Sometimes it is argued that you must follow your dream, or dreams. This assumes that you know your dreams. Do you know your dreams, really?
You do something you wanted to do for a long time, only to find out, after doing it a few times, that you don’t want to do it anymore, and that it is not your dream.
So what? It’s good that you found out and can move on.
To know your dreams doesn’t matter. To know that you’re not caught in someone else’s dream does, and it is easier to assess if you pay attention.
In cartography, a map has no start and no end. The same is true for the process of living.
