I only achieve simplicity with enormous effort.

The only lasting truth is change.

Human beings must always be on the watch for the coming of wonders.

Learning never exhausts the mind.

I found my place when I stopped looking for it.

Somewhere, something incredible is waiting to be known.

Joy is not in things, it is in us.

Resilience — the ability to brush off pain.

Do not whine... Do not complain. Work harder. Spend more time alone.

A genuinely happy person is one who has rendered others happy.

I find the great thing in this world is not so much where we stand, as in what direction we are moving.

All experience is great providing you live through it.
