When one door of happiness closes, another opens; but often we look so long at the closed door that we do not see the one which has been opened for us.

Where you stumble, there lies your treasure.

Beauty is all around us amidst strife and turmoil to be seen by those who look not to those who wish.

If you break your neck, if you have nothing to eat, if your house is on fire, then you got a problem. Everything else is inconvenience.

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

Your success is not determined by external factors; it's determined by your inner drive and resilience.

Never interrupt someone doing what you said couldn't be done.
