I'm a science writer, published author - my book M(other)land was published by Penguin Random House - and freelance coach who's been riding the freelance rollercoaster on and off since 2005.

I've lived every freelance nightmare imaginable -  from working until 3AM on Christmas Eve for a client (while at my parents' house, on their rickety old computer), to being too terrified to raise my rates, to feeling physically sick every time I tried to post about my work online.

But I've also built a freelance business that gives me the freedom to work in my pyjamas, earn a proper income, and actually take holidays without my laptop (revolutionary, I know).

The methods I'll share in this challenge aren't theoretical professor-type waffle – they're the exact approaches I've used to transform my own freelance life and help hundreds of other women do the same.
