Causal inference is not just about statistical significance; it's about understanding the mechanisms behind the numbers.

The known is finite, the unknown infinite; intellectually we stand on an islet in the midst of an illimitable ocean of inexplicability.  

The most successful people in life are the ones who ask questions. They’re always learning. They’re always growing. They’re always pushing.

I think the best thing you can do is to be true to yourself.

如果你不前进，你就在落后。
