I think you need to have a day or two when you treat yourself, because it brings happiness, it stimulates your mind.
The period from conception to two is about the development of a baby's emotional capacities. Mum saying, 'Oh, darling, I love you,' and singing baby songs and pulling faces literally stimulates the synapses in the brain.
I think if the movie has resonance and stimulates the viewer to talk about it, you can have as large an audience as you want. The most important thing for me is that the movie exists. And that's success enough already.
But investment in space stimulates society, it stimulates it economically, it stimulates it intellectually, and it gives us all passion.
Engineering stimulates the mind. Kids get bored easily. They have got to get out and get their hands dirty: make things, dismantle things, fix things. When the schools can offer that, you'll have an engineer for life.

I couldn't imagine a day without music. It relaxes and stimulates me in equal measure and I hate the sound of silence - the concept, I mean, not the track by Simon and Garfunkel.
I've always found diversity more interesting than specialisation. I like mixing it up across years, within days, within weeks - that's what stimulates me, gives me energy.
