She wasn’t afraid of difficulties; what frightened her was being forced to choose one particular path.
Choosing a path meant having to miss out on others. She had a whole life to live and she was always thinking that, in future, she might regret the choices she made now.
‘I’m afraid of committing myself,’ she thought to herself. She wanted to follow all possible paths and so ended up following none.
Even in that most important area of her life, love, she had failed to commit herself. After her first romantic dissappointment, she had never again given herself entirely. She feared pain, loss and separation. These things were inevitable on the path to love, and the only way of avoiding them was by deciding not to take that path at all. In order not to suffer, you had to renounce love. It was like putting out your own eyes in order not to see the bad things in life.
