Alone we can do so little together we can do so much.

I love to be alone. I never found the companion that was so companionable as solitude.

It is strange to be known so universally and yet to be so lonely.

We are all sentenced to solitary confinement inside our own skins, for life.

All men's misfortunes spring from their hatred of being alone.

The time you feel lonely is the time you most need to be by yourself.

Love is our true destiny. We do not find the meaning of life by ourselves alone - we find it with another.

All men's miseries derive from not being able to sit in a quiet room alone.

Always give a word or sign of salute when meeting or passing a friend, or even a stranger, if in a lonely place.

Look at the sky. We are not alone. The whole universe is friendly to us and conspires only to give the best to those who dream and work.
