Mathematics is not just about numbers, equations, computations, or algorithms: it is about understanding.

在商業(yè)中，就像在生活中一樣，你必須相信自己的直覺(jué)并承擔(dān)經(jīng)過(guò)計(jì)算的風(fēng)險(xiǎn)。

The way we see things is affected by what we know or what we believe.

"The only way to get rid of a temptation is to yield to it."
