Life is to be fortified by many friendships. To love and be loved is the greatest happiness of existence.

Love is like war: easy to begin but very hard to stop.

In science as in love, too much concentration on technique can often lead to impotence.

Love is fire. But whether it's gonna warm your heart or burn your house down you can never tell.

Love can never grow old. Locks may lose their brown and gold. Cheeks may fade and hollow grow. But the hearts that love will know, never winter's frost and chill, summer's warmth is in them still.

Perfect love is rare indeed - for to be a lover will require that you continually have the subtlety of the very wise, the flexibility of the child, the sensitivity of the artist, the understanding of the philosopher, the acceptance of the saint, the tolerance of the scholar and the fortitude of the certain.
