Great advice for all children, from US Justice of the Supreme Court Sonia Sotomayor, as shared in the New York Times:
You should always dream big.
Never let anyone say that you can’t do it. And the minute they say that, say: “You are telling me I can’t do it? Well, I’ll show you I can.”
You have to study, study, and study. That’s the only way you can achieve what you want in life. Education is the key to the future.
You have to work very hard. In life no one will give you anything for free. You must earn every single thing in this life.
