I know from my own experience that there is much more to 'intelligence' than an IQ number. In fact, I hesitate to believe that any system could really reflect the complexity and uniqueness of one person's mind, or meaningfully describe the nature of his or her potential.

I thought of the infinitely many points that can divide the space between two human hearts.

We know next to nothing with any certainty about Pythagoras, except that he was not really called Pythagoras. The name by which he is known to us was probably a nickname bestowed by his followers. According to one source, it meant ‘He who spoke truth like an oracle’. Rather than entrust his mathematical and philosophical ideas to paper, Pythagoras is said to have expounded them before large crowds. The world’s most famous mathematician was also its first rhetorician.

I consider social skills a bit like learning a language. I've been practising it for so long over so many years I've almost lost my accent.

No relationship is without its difficulties and this is certainly true when one or both of the persons involved has an autistic spectrum disorder. Even so, I believe what is truly essential to the success of any relationship is not so much compatibility, but love. When you love someone, virtually anything is possible.

I had eventually come to understand that friendship was a delicate, gradual process that mustn’t be rushed or seized upon but allowed and encouraged to take its course over time. I pictured it as a butterfly, simultaneously beautiful and fragile, that once afloat belonged to the air and any attempt to grab at it would only destroy it.

My algebra was relatively poor. I found it very difficult to use equations that substituted numbers - to which I had a synesthetic and emotional response - for letters, to which I had none. It was because of this that I decided not to continue math at Advanced level, but chose to study history, French and German instead.
