To be here in this one moment.

Whenever things seem absolutely terrible, to see that you’re alive and that’s all that matters.

I believe in this country. I believe in the American people. I believe that people are more good than bad. I believe tragic things happen, I think there's evil in the world, but I think that at the end of the day, if we work hard, and if we're true to those things in us that feel true and feel right, that the world gets a little better each time.

It is necessary, I believe, to accept this idea, not only for science, but also for other things; it is of great value to acknowledge ignorance.  It is a fact that when we make decisions in our life we don't necessarily know that we are making them correctly; we only think that we are doing the best we can – and that is what we should do.

I find it difficult to sit still.

A really bad habit of eating sweets before I go to sleep.

I was a happy kid. I had quite a small life: I grew up in Walthamstow and didn’t really leave east London. I didn’t go to the South Bank for the first time until I was 18 years old.

In order to raise money to pay for myself to go to the National Youth Theatre, I performed a medley of my drama school speeches and some songs for my entire school. Considering I can’t sing, this was terrible. I did U Remind Me by Usher and Hey There Delilah by the Plain White T’s. They paid £2 each – basically, to laugh at me.

Called me the N-word.

After losing my mum still managing to finish drama school, because that was really difficult. I lost her in the first year.
