The only real progress lies in learning to be wrong all 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.

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

If you are lonely when you're alone, you are in bad company.

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

I don't want to be alone, I want to be left alone.

If it's true that our species is alone in the universe, then I'd have to say the universe aimed rather low and settled for very little.

Yes, I guess you could say I am a loner, but I feel more lonely in a crowed room with boring people than I feel on my own.

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

Before the throne of the Almighty, man will be judged not by his acts but by his intentions. For God alone reads our hearts.
