In Genesis, it says that it is not good for a man to be alone but sometimes it is a great relief.
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.
I love to be alone. I never found the companion that was so companionable as solitude.
