人在幼年時，精神專注敏銳，成年后思想容易分散，因此教育要趁早，不可錯過時機。

Money is overrated. Truly new things rarely need an abundance of money. If that was so， billionaires would have a monopoly on inventing new things， and they don’t. Instead almost all breakthroughs are made by those who lack money， because they are forced to rely on their passion， persistence and ingenuity to figure out new ways. Being poor is an advantage in innovation.

The past is always present, and the present is always past.

創新不是顛覆，而是持續優化。
