I have to remember the good people in the world outnumber the bad people. I think when you start to feel frustrated or you have no hope left in humanity or whatever, you've got to just remember that there are people out there who are working incredibly hard to get a positive message across.
And I know I can do this because I went to London on my own, and because I solved the mystery…and I was brave and I wrote a book and that means I can do anything.
