Success is not final, failure is not fatal: it is the courage to continue that counts.

The secret to happiness is to face the fact that the world is horrible.

Failure gave me an inner security that I had never attained by passing examinations. Failure taught me things about myself that I could have learned no other way. I discovered that I had a strong will, and more discipline than I had suspected; I also found out that I had friends whose value was truly above the price of rubies.

Some people go to priests; others to poetry; I to my friends.

我拒绝接受人类的末日。

Technology will be the great enabler of our net-zero ambitions.
