试图独自生活的人不会成功。如果他的心不回应另一颗心，他的心就会枯萎。如果他只听到自己思想的回声而找不到其他灵感，他的思想就会萎缩。
The danger of the past was that men became slaves. The danger of the future is that men may become robots.
The challenge of creating efficient and selective catalysts keeps me motivated every day.
I don't believe in luck. I believe in preparation meeting opportunity.
