If you make friends with yourself you will never be alone.

Only the lonely know the way I feel tonight.

Be able to be alone. Lose not the advantage of solitude, and the society of thyself.

The longer one is alone, the easier it is to hear the song of the earth.

All of our unhappiness comes from our inability to be alone.

When the people you love are gone, you're alone.

You can't fake it when you're alone with God, you know.

Nothing makes us so lonely as our secrets.

If you're going to put yourself above everybody else, you might end up alone.

By all means use some time to be alone.
