If I could know three things, I’d have a hard time choosing between three self-based questions and three curiosity-based questions
Self based
1. Will I ever be healthy?
2. How could I live my life in order to optimize my usefulness to society?
3. How could I live my life in order to optimize my happiness?
Curiosity based
1. Is there extraterrestrial life?
2. Is there a god?
3. Is the universe deterministic?
