When Josh Littlejohn started a small sandwich shop in his home city of Edinburgh, he would never have thought that, within ten years' time, it would be frequented by Hollywood megastars, that he would have opened a string of successful cafés across the UK, and that he would be honoured with an MBE by the Queen. Not to mention raising over £25 million to combat homelessness around the world. And all set in motion by a person in a situation of homelessness, named Pete, walking into his café one day and sheepishly asking for a job.

Paying It Forward is part memoir, part manifesto for social entrepreneurship, and part manual for putting purpose ahead of profit. It reveals what social entrepreneurship is and how it can make a difference. How if only 20% of entrepreneurs became social entrepreneurs our world would be in a much better state. How we can 'Calculate Risks', why we should 'Help Just One Person' every day, and that 'If You Don't Ask, You Don't Get'.
