Mathematics is not a careful march down a well-cleared highway, but a journey into a strange wilderness, where the explorers often get lost.
数学不是沿着一条清理干净的高速公路小心翼翼地行进,而是一次进入陌生荒野的旅程,探险者常常会迷路。
The more you lose, the more you learn.
I’m not a role model, I’m just a guy who made it.
所有的大人起先都是孩子,但愿我们都能记住这一点。
最大的风险是不冒任何风险。
