I think the true test of a pop song, for me, and I've talked to a lot of other writers about this, is you take your demo, you pop it in your car and you drive down Sunset Blvd. to Santa Monica, and that's the Hollywood car test.

I knew I could make money from songwriting, so how much and when was not really the question.

When you're around enormously successful people you realise their success isn't an accident - it's about work.

So for every day that you're on this earth, for every minute that you have, the whole idea is doing nothing less than exactly what you feel you're supposed to do and squeezing every last drop out of life every day, regardless of the difficulties or trials that you face.

I have a theory that you can decide to make whatever day it is a good day.
