'Sometimes it's just writing to get it out... you can almost interrogate it more. You can hold it in your hand and you can explore it and you can look at it and then maybe it becomes something or maybe it doesn't.'

Having a good idea is a great place to start when you're writing a business book. But it's only a start. Then comes the real work: testing that idea out, articulating it clearly, and - perhaps hardest of all - drawing out the 'so what?' 

Andy Brown has been through all these stages with The Emotional Overdraft - from recognising that business growth often has a human cost that's hidden from the balance sheet but is no less real for that to developing effective metrics to help leaders manage that cost for themselves and their people. 

If you're a 'doer' whose go-to answer is 'just work harder' or a writer struggling to develop your idea or - even better - both, this is for you.
