当帮助人们摆脱贫困陷阱时，微小的改变可以产生巨大的影响。
Small changes can have big effects when they help people break out of the poverty trap.
I believe that man will not merely endure: he will prevail. He is immortal, not because he alone among creatures has an inexhaustible voice, but because he has a soul, a spirit capable of compassion and sacrifice and endurance.
The application scenarios of drones far exceed our imagination.
The best argument I know for an immortal life is the existence of a man who deserves one.
