Every heart that has beat strongly and cheerfully has left a hopeful impulse behind it in the world, and bettered the tradition of mankind.

It is only in sorrow bad weather masters us in joy we face the storm and defy it.

Nurture your minds with great thoughts. To believe in the heroic makes heroes.

Someone's sitting in the shade today because someone planted a tree a long time ago.

You don't look out there for God, something in the sky, you look in you.

Change your thoughts and you change your world.

You change your life by changing your heart.

Tears of joy are like the summer rain drops pierced by sunbeams.

It is not ignorance but knowledge which is the mother of wonder.

As knowledge increases, wonder deepens.
