It is the glory of London that it is always ending and beginning anew, and that a visitor, with a good eye and indefatigable feet, will find in her t… - Anna Quindlen

Here is my favorite biblical direction: Be not afraid. It's truly the secret of life. Fear is what stunts our growth, narrows our ambitions, kills our dreams.

So fear not.

...You are surely afraid: of leaving what you know, of seeking what you want, of taking the wrong path, of failing the right one. But you can't allow any of that to warp your life. You must have the strength to say no to the wrong things and to embrace the right ones, even if you are the only one who seems to know the difference, even if you find the difference hard to calculate.

Acts of bravery don't always take place on battle fields. They can take place in your heart, when you have the courage to honor your character, your intellect, your inclinations, and yes, your soul by listening to its clean, clear voice of direction instead of following the muddied messages of a timid world. So carry your courage in an easily accessible place, the way you do your cellphone or your wallet. You may still falter or fail, but you will always know that you pushed hard and aimed high. Take a leap of faith. Fear not. Courage is the ultimate career move.

Set aside the old traditional notion of female as nurturer and male as leader; set aside, too, the new traditional notion of female as superwoman and male as oppressor. Begin with that most frightening of all things, a clean slate. And then look, every day, at the choices you are making, and when you ask yourself why you are making them, find this answer: Because they are what I want, or wish for. Because they reflect who and what I am.

This is the hard work of life in the world, to acknowledge within yourself the introvert, the clown, the artist, the homebody, the goofball, the thinker. Look inside. That way lies dancing to the melodies spun out by your own heart.

Behind every door in London there are stories, behind every one ghosts. The greatest writers in the history of the written word have given them substance, given them life.

And so we readers walk, and dream, and imagine, in the city where imagination found its great home.
