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得很好的高速公路小心行进,而是一次进入陌生荒野的旅程,探险者常常会迷路。
I encourage you to accept that you may not be able to see a path right now, but that doesn’t mean it’s not there.
生命短暂,让它甜美。
