Happiness is a choice that requires effort at times.
God loves to help him who strives to help himself.
He who learns must suffer. And even in our sleep, pain that cannot forget, falls drop by drop upon the heart, and in our own despair, against our will, comes wisdom to us by the awful grace of God.
Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution.
