I'm not afraid of storms, for I'm learning how to sail my ship.
To me, fearless is not the absence of fear. It's not being completely unafraid. To me, fearless is having fears. Fearless is having doubts. Lots of them. To me, fearless is living in spite of those things, every single day.
——《在东京(民报)创刊周年庆祝大会的演说》(1906年12月2日)
The more you read, the more things you will know. The more that you learn, the more places you'll go.
A good mathematician is not one who knows all the answers, but one who asks the right questions.
