Endorsed by the likes of Sir James Dyson, Deborah Meaden and Sir Ranulph Fiennes, Stop Talking Start Doing, Shaa describes the book as "A kick in the pants in six parts".
She says: "If there is something you really want to do, but secretly fear you'll never do it, then you need this. This is your kick in the pants. To make your thing happen, you have to climb into the ring. You have to face your fears and move from talking to doing.
"Of course, it's right and natural to have fears, but understanding them will keep you on top. And then you'll find that starting can instantly make things change. So say farewell to the status quo.
"And that's the trick, you see. Simply start somewhere. Anywhere. But do it now. For those working for others or for themselves, for those in love or out of love, for those who are artistic or scientific, the busy and the clock-watchers… but mostly for those with ambition: This is what you need to start."
