This world, after all our science and sciences, is still a miracle; wonderful, inscrutable, magical and more, to whosoever will think of it.

Loneliness is painful; solitude is peaceful.

Science can lift people out of poverty and cure disease. That, in turn, will reduce civil unrest.

Happiness is the new rich. Inner peace is the new success. Health is the new wealth. Kindness is the new cool.

Your ability to manage and leverage your resources effectively, including time, energy, and relationships, drives your success and amplifies your impact.

There's no repentance in the grave.

I'm actually as proud of many of the things we haven't done as the things we have done.
