The attentions of others matter to us because we are afflicted by a congenital uncertainty as to our own value, as a result of which affliction we tend to allow others' appraisals to play a determining role in how we see ourselves. Our sense of identity is held captive by the judgements of those we live among.

Objectively good spaces to work rarely end up being so; in their faultlessness, quiet and well-equipped studios have a habit of rendering the fear of failure overwhelming. Original thoughts are like shy animals. We sometimes have to look the other way - towards a busy street or terminal - before they run out of their burrows.

One of love's greatest drawbacks is that, for a while at least, it is in danger of making us happy.

What I want to argue for is not that we should give up on our ideas of success, but that we should make sure that they are our own. We should focus in on our ideas and make sure that we own them, that we're truly the authors of our own ambitions. Because it's bad enough not getting what you want, but it's even worse to have an idea of what it is you want and find out at the end of the journey that it isn't, in fact, what you wanted all along.

Let's say you went to Harvard or Oxford or Cambridge, and you said, 'I've come here because I'm in search of morality, guidance and consolation; I want to know how to live,' - they would show you the way to the insane asylum.

At the heart of every frustration lies a basic structure: the collision of a wish with an unyielding reality.

I feel that the great challenge of our time is the communication of ideas.
