Personal finance journalist Michelle McGagh is no stranger to writing about the merits of saving. But how much did she really know about her own spending? Last year, she set herself the challenge of only spending money on essentials for a year. Her challenge to stop “squandering” money became a book called The No Spend Year, and saved her £22,000. Michelle has spent more than a decade writing for titles such as The Guardian, City Wire, AOL and Money Observer.
