I've always felt that if you back down from a fear, the ghost of that fear never goes away. It diminishes people. So I've always said 'yes' to the thing I'm most scared about. The fear of letting myself down - of saying 'no' to something that I was afraid of and then sitting in my room later going, 'I wish I'd had the guts to say this or that' - that galvanizes me more than anything.
