This in not about tonight. Sometimes, you can look back at what you did and said and you can think 'I could not have said or done anything differently. I didn't hold back. I gave it my all. I was honest and positive and optimistic.' And when you do that you might wonder how it didn't work out. Surely if everything was right then it should have worked out? And you wonder whether you can ever trust life to be fair. How can it go wrong? What is worth doing if this is going to happen? Why does it work out for careless and unpleasant people who don't do it right? Why do dreams not come true even when they seem like they can?

And the answer is that there is no answer. Look at history all you like, there's no perfect formula. You can't make it work by numbers. It's just luck. In fact you can only define the successful formula after it happens to have been a success. And you cannot make it happen again at will. It's just down to luck. That's life.

And sometimes, life hurts.
