When I was first approached about doing an autobiography, I said, 'absolutely not.' But when I sat down, memories came pouring out. It wrote very quickly - I think there was an emotional impulse, because once I started in, the story itself carried me along. It was a very intense writing period and took a year and change to finish.

It's important always to have a sense of wonder.

I think everybody encounters difficulty. It's just more pitched in some people.

Growth is an erratic forward movement: two steps forward, one step back. Remember that and be very gentle with yourself.

I do a lot of co-writing with my producer RedOne, and then a lot on my own. I just like to be creative.

I just had to find something else to fulfill me. Always being a singer and writing, it was a blessing. My brother started making music that was the kind of music I always saw myself singing.

My cure for writer's block is to step away from the thing I'm stuck on, usually a novel, and write something totally different. Besides fiction, I write poetry, screenplays, essays and journalism. It's usually not the writing itself that I'm stuck on, but thing I'm trying to write. So I often have four or five things going at once.

I love film criticism as an art. I think it's a very important thing.
