That’s been one of my mantras—focus and simplicity.Simple can be harder than complex，you have to work hard to get your thinking clean to make it simple.

The pursuit of mathematical knowledge is a never-ending adventure, filled with challenges, surprises, and the satisfaction of solving the unsolvable.

O sonho é a matéria-prima da realidade.

我是个斗士，我相信积极和努力的力量。
