My five year-old cousin wouldn’t go to sleep because he wanted to keep looking at the stars and my aunt tried to bribe him with a piece of chocolate and he just said “Would you rather get a reward or be happy” and turned back to the window.
My 3yo said she wanted to be an astronaut, and I said she had to study hard, go to college, learn a lot of science, and take a physical fitness test, and she shrugged and said, "That's just 4 things." So she's basically a nonchalant motivational speaker.
