Unless we love and are loved, each of us is alone, each of us is deeply lonely.

The best part about being alone is that you really don't have to answer to anybody. You do what you want.

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

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

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

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.

Only the lonely know the way I feel tonight.

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

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.

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